First law of thermodynamics(0305)

                    First Law of Thermodynamics


W = Integral(F) dx =integral (P)dV


Water Vapor's Work experiment 


The answer is that the heat release will both change the internal energy (the temperature of water) and push the piston upwards

 what activity produces near zero internal energy (our answer is: walking very slowly) and what activity produces near zero work done (answer is sleeping)

Here is our derivation of how to find the work done. Note that we use linear expansion instead of volume expansion, to offset this error, we simply multiplied the answer by 3 at the end. The final answer is 0.0173 J, which was right.


Derivation to find the root mean square velocity.

Relationship between delta (V)/V and delta (T) /T




Our calculation to find the final temperature inside the syringe.
