3
IN A gas follows the cycles shown. How much work is done?

4
Objective: To find out how the conservation of energy applies to thermodynamics

5
Homework check

6
Conservation of Energy ΔPE + ΔKE + ΔU = 0

7
James Prescott Joule

9
Work in thermodynamic processes W=FΔd W=PAΔd W= - PΔV

10
PV diagram

11
First law of Thermodynamics ΔU = Q + W

12
Isovolumetric (volume constant) ΔU = Q

13
Isothermal (temperature constant) ΔU = 0 Therefore Q = W

14
Isobaric (pressure constant) ΔU = Q + W

15
Adiabatic (thermally isolated system) ΔU = W

16
Processconditions first law Isobaricboth temp ΔU=Q+W and volume change Isovolumetricno workΔV=0 so W=0 so ΔU=Q Isothermalno change ΔU=Q+W=0 in T or U so Q= - W Adiabaticno energyQ=0 transfer asso ΔU=W heat

17
PV diagrams and thermodynamic processes (quick quiz 12.2) Identify the paths

18
Problems White board these problems together: 50, 51, 54

19
Out: Which of these processes are isothermal, isovolumetric, or adiabatic: a)A tire being rapidly inflated b)A tire expanding gradually at a constant temperature c)A steel tank of gas being heated
