Part A. You warm 1.85kg of water at a constant volume from 21.5C to 29.0C in a kettle. For the same amount of heat, how many kilograms of 21.5C air would you be able to warm to 29.0C? Make the simplifying assumption that air is 100% N2.
Part B. What volume would this air occupy at 21.5C and a pressure of 1.08 atm
