## Essential University Physics: Volume 1 (3rd Edition)

We must divide the rate at which the people increase the temperature of the house by the rate at which the heat leaves the house to find how much warmer the house will be than outside. Thus, we find: $T = \frac{36 \times 100}{320} = 11.25$ Adding this to the 8 degree temperature outside, we find that the temperature will be around 20 degrees Celsius. This will be slightly below room temperature, which is around 25 degrees Celsius, but the house will still be comfortable.
