PV work
Use w=–Pex ΔV to calculate work

  1  

PV work Example 2
Reversible heating of a gas at constant pressure.

  1  

PV work
Follow up from lecture notes (8/28, slide 40). Discusses how to avoid rounding errors.

  1  

Calorimetry
Follow up from lecture notes (8/30, slide 63). Calculates the specific heat of a metal.

  2  

q, w, ΔU and ΔH of reversible heating of an ideal gas at constant pressure
Tinoco's textbook. Chapter 2, problem 7.

  2  

Mixing ice and water - Calorimetry
Tinoco's textbook. Chapter 2, problem 12.

  3  

ΔU and ΔH of a reaction from tabulated ΔH values of formation
Uses Cp data to calculate ΔU and ΔH at another temperature.

  4  

ΔS and ΔH of a reaction from tabulated data
Uses Cp data to calculate ΔS and ΔH at another temperature. The part of the problem that discusses ΔH is part of HW4. The part about entropy is part of HW5.
