A person living in a 5m × 5m × 5m room turns on a 130 W fan before he leaves the warm room at 100 kPa and 30 °C, hoping that the room will be cooler when he comes back after 5 hours. Disregarding any heat transfer and using the PG model for air on TESTCalc, answer the following questions. (Figure 1)

Question
I am trying to find the temperature of the room after 5 hours
the room has a volume of 5 m^3 with an initail pressure of 100 kPa and 30 deg C. There is also a 130 Watt fan that is running in the room for the duration of that time.
I am trying to find the final temperature of the room but I keep getting final temperatures such as 800 deg C.
