Question

A 0.2 m^3 oven is heated from 20◦C to 200◦C. The initial pressure inside the oven (same as outside is 950 hPa).

a) If the oven is sealed (i.e., density does not change), how much heat is added to the oven?

b) Most ovens end up leaking air out into the environment in a way that maintains the pressure. How much heat is added to increase the temperature in this case? As a reminder, you need to account for the air that escapes from the oven by integrating.
