Homework Statement
An office with a volume of 52.5 m^3 uses a heat engine that outputs 1200 W. Suppose that, initially, the office has a pressure of 1 atm and 20 degrees Celsius before the heater is turned on. After 10 minutes (6000 seconds), what is the final air temperature?

1 atm = 101325 Pa
20 + 273 = 293 K
Q = mc*ΔT ?
The Attempt at a Solution
At first, I thought this was a simple heat problem. I used the density of air and the volume to get a mass of 64.3125 kg. However, our book does not list the specific heat capacity of air, and I feel the answer I get may be a little contrived if I used values found on Google instead of using the variables given in the problem. However, I feel I may be using the wrong equation. I searched through my textbook and lecture notes, but I couldn't find any equations that I thought were relevant to the problem or had variables I could solve for with the given information. What is the equation I am supposed to be using here?
