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.
