Compute the specific heat capacity at constant volume of nitrogen (N2) gas. The molar mass of N2 is 28.0 g/mol.

You warm 2.00 kg
of water at a constant volume from 22.5 ∘C to 32.0 ∘C in a kettle. For the same amount of heat, how many kilograms of 22.5 ∘C air would you be able to warm to 32.0 ∘C? Make the simplifying assumption that air is 100% N2.

What volume would this air occupy at 22.5 ∘C and a pressure of 1.00 atm ?
