30 people gather in a 1`0 m xx 5 m xx 3 m` room for a confidential meeting. The room is completely sealed off and insulated. Calculate the rise in temperature of the room in half an hour. Assume that average energy thrown off by the body of a person is 2500 kcal/day, density of air is `1.2 kg/m^(3)` and specific heat specify capacity of air at constant volume is `0.24 k cal kg^(-1) . ^(@)C^(-1)`. Neglect volume occupied by human bodies.

Answer

`36^(@)C`
