(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A Fan draws electricity at a rate of 1.5kW.

The fan is in a well insulated rigid container of air with volume 60 m^3.

Initial pressure and Initial Volume are: P1 = 1 atm, T1 = 27 degrees C.

After 30 minutes, assume Ideal Gas behavior, determine the final Temp and final Pressure.

2. Relevant equations

ΔE = Q - W

PV=nRT

ΔU=mc(T2-T1)?

3. The attempt at a solution

I calculated the energy into the system to be 2700.8 kJ after 30 minutes. Since there is no ΔKE or ΔPE, ΔE = ΔU = 2700.8 kJ. Since it is well insulated, Q = 0. So W = -2700.8 kJ.

I am having trouble linking the relationship between Energy and Temperature/Volume. I am not sure what other equations to use, so I am making no progress on this problem.
