Flash - Enthalpy Opening Sequence This took me wayyyyy too long, but I enjoyed making it! I'm surprised I was actually patient enough to finish it. Anyway, it's a test opening sequence to my story/manga... and it's based on ppl in real life. Ignore the watermark =__=;; I was too lazy to export it as .avi thru flash and also that means I have to convert a lot of the objects into graphics and blah blah blah. But it sux that the swf to video conversion tool captured all the lagging too =__=;; o wells. Flash ver: Song: Kotoko - Blaze Read the Manga: enthalpy- Other videos of this anime

Calorimetric determination of Enthalpy of Combustion Early experimental effort at providing home tuition in chemistry via YouTube. Please visit for later efforts using a better video camera. A simple calorimetric approach is used to determine the molar enthalpy change of combustion of methanol. This videoclip looks at the practical details and the mathematical calculations used to get joules from temperature change. 0.6g of methanol (CH3OH) is burned - causing the temperature of 100g of water (specific heat capacity 4.2J/g/K) to rise by 20 celcius. The enthalpy change is determined to be -420 kJ/mol. This value will be lower than expected due to heat losses to the surroundings. Apologies for the poor quality of the video and the very basic form of presentation used. If it's a topic that's causing you difficulties, perhaps it will be of some help. Rgds FS

Use of Bond Energies to determine Enthalpy of Combustion Early experimental effort at providing home tuition in chemistry via YouTube. Please visit for later efforts using a better video camera. Determination of the approximate enthalpy change of combustion of methane using average bond energy terms. This method gives an estimate of the reaction's enthalpy change. For example, CH bonds appear in many differnt compounds. The surrounding groups can influence the strength of bonds. Chemists have assigned an average bond energy to each bond to allow them to be used to estimate enthalpy changes for reactions. To find a really exothermic reaction one wants a reaction where the reactants have relatively weak bonds and the products relatively strong bonds.

Enthalpy (My anime/manga) artworks Before asking questions, READ THE DESCRIPTIONS Ahem. Thank you. Hi. I semi-apologize for this lame upload. However I feel that I should upload something art related since I haven't done that since... man, last summer? And also I've been getting msgs from a couple of ppl about this anime/manga of mine, so here are some submissions related to it, although there's nothing new here. But people on youtube probably haven't seen these. For those who subscribed for music, well, erh... this song is by me, from a long time ago tho. It's called "The Dark Side", it's up on my site at Anyway, these are just artworks for my anime "Enthalpy". Annotations will explain stuff =_=;; Most of these artworks are from years ago. All the drawings are up on my DA at Other videos related to this manga Thanks for the comments n stuff. Knowing the ppl actually know about my manga and wanna see stuff from it really helps keep the production going. Most of my real life friends don't know about this kuz... erh... they're not artistic and aren't into these things =_=;; and I feel awkward showing my productions (music and art) to most of them =____=;; Especially if they're like... sitting beside me....

2. Hess Cycles and Enthalpy Level Diagrams (2) Visit for notes on this topic. Thanks for watching! A basic explanation of how Hess' law allows you to calculate the enthalpy change of a reaction if you know the enthalpy change associated with forming the reactants from their constituent elements and the enthalpy change associated with forming the products from their constituent elements.
Hess Cycle: Enthalpy of formation of Ethanol - Long method Early experimental effort at providing home tuition in chemistry via YouTube. Please visit for later efforts using a better video camera. To get an enthalpy of formation from 3 enthalpies of combustion. While the short method is usually best, it assumes that the oxygen atoms balance. Here, on one occasion, an effort is made to show that everything does tally up. This method is like algebra - you add, multiply and rearrange chemical equations! I have provided a help sheet here: Answer should be displayed like this: Enthalpy = (-786)+ (-858) + (1371) = -273 kJ/mol The marker can quickly see where any mistake has been made - thus awarding some marks for an incorrect final answer!

Determine the Enthalpy change in hydration of Anhydrous Magnesium sulfate (MgSO4) IMPORTANT: All content here meant to be Educational,None of the above experiment should be repeated on your own. This is a video about how to determine the Enthalpy of hydration, I take Magnesium sulfate as an example to illustrate how it is determined. Hydrated MgSO4 and Anhydrous MgSO4 is dissolved seperately and temperature change is recorded, DeltaH of Anhydrous MgSO4 - DeltaH of Hydrated MgSO4 = Enthalpy of hydration.

Enthalpy and Enthalpy Change .mp4 is where to download the entire video. This video clearly explains what enthalpy is and what is meant by enthalpy change (⌂H). Using graphs and easy to read equations, you are shown how enthalpy is involved in endothermic and exothermic reactions. Two different methods for showing enthalpy changes are explained: Writing ⌂H beside an equation, and putting a "heat term" right in the equation. You are shown how to use these methods to determine whether a reaction is endothermic or exothermic.
Reaction Enthalpies In this video I use Hess Law to determine the total energy involved in a combustion reaction. This is a bit more challenging than my other Hess Law video

Autotune test/Enthalpy Song - Self Reflection Before autotune bashing, plz read description. Yeah so I've jumped on the autotune band waggon... and I know the whole blah blah blah autotune requires no talent whatever... =_=;; anyway, I know I can't sing, I'm just trying autotune out for fun... plus this is totally original in that I wrote the song and lyrics. Anyone who wish to give singing this a shot can d/l the instrumental version below. My voice sux so much that even autotune can't help it much XD plus I recorded whilst having a horrible cold =_=;; Tis a song w/ lyrics for my manga Enthalpy. The song will be an insert song in a very very distant future scene. Erh..... I was aiming for the epic imagery kinda lyrics... and I rarely write so hopefully the lyrics make sense XD As much as lyrics usually make sense anyway. Lyrics: A shattered mirror standin' before me, I'm looking right at it and here's what I see.... A distorted image of who I am today a broken version of who I want to be I hold on tightly to the broken glass Dissecting myself cutting me slowly At least this way I'll be completely broken So I can rebuild myself all anew Sorry... is all that I could say to myself only... if I wasn't so blind and weak forgive me... that I'm not someone I'm proud to be lately... I've lost myself and Every time the rain falls down I'd walk by myself down town On the ground where I stood are one thousand more mirrors to look through In the waters I see the old me Looking back disappointedly Until another rain drop falls ...
Heat and Enthalpy This General Chemistry lecture covers the First Law of Thermodynamics. We discuss the equivalence of heat, work and energy, the definitions of thermodynamic state functions, and the relationships between internal energy, enthalpy and heat capacity.
Enthalpy - Mock/Test Finale (Major spoiler?) MUSIC _NOT_ BY ME!! Nic Chagall - This Moment Usually I use my own material, but w/ these test scenes I'm too lazy to compose my own stuff. I wasn't gonna submit this anywhere at first.. but then I found out I got 300 subs so I felt like I should submit smth Oo;; and if I don't submit this I don't know when I'll have something else to submit here. Meh, it was more or less a test of screenplay/timing. I actually got the idea of trying this when I first found the song, kuz it suited the ending very much (although when the time comes for me to do the real ending I'll have to use my own songs). I don't know if I'll actually use this ending (probably not, but something similar to this maybe), kuz it's um.. kinda way too bittersweet & disappointing =_=;; Eeek, it's kind of a Naruto and Sasuke moment LoL. The animation's not that great, kuz this is more of a test. As well the credits are just for show I had to blur out a lot of the names kuz they had full names of actual people XD Read Manga: enthalpy- more info Lyrics All that I need is this moment To send me away with a smile on my face All that I seek is this moment All day in my mind I recreate I tried to leave but I turn back On my heart remains a trace All that I seek is this moment All day in my mind I recreate If there was a way to get back This feeling of chase..of chase Ive been flying with broken wings And now Im falling faster to the ground And its a bitter end to a story so ...
