A group of 50 persons attend a secret meeting in a room which is 12 m wide by 10 m long and a ceiling height of 3 m. The room is completely sealed off and insulated. Each person gives off 150 kCal per hour of heat and occupies a volume of 0.20 m³. The room has an initial pressure of 101.3 kPa and temperature of 16°C. Calculate the room temperature after 10 minutes. Use R=0.287 kJ/kg-K and Cᵥ=0.171 kCal/kg-K. (4 decimal places)
