AP Unit II C 2. Laws of Thermodynamics Ref: Chapter 12. a) Students should know how to apply the first law of thermodynamics, so they can: (1) Relate the heat absorbed by a gas, the work performed by the gas, and the internal energy change of the gas for any of the processes above.

Laws of Thermodynamics
Ref: Chapter 12
What are the values of each of the following (a) Temperature at a and b b) Work done by the gas during ab
c) Heat added to the gas during ab d) change in internal energy of gas
1.5 x 105 Pa
V (x10-3 m3
R in Physics is 8.31 j/mol K. In chemistry they use J/liters K. If 1 mol of gas is 22.4 liters, what will be R in chemistry?
= (QH – QC)/QH = 1- QC/QH
Efficiency is always less than one!!!!!!!
= (TH – TC)/TH = 1- (TC/TH)
