An audience of 1800 fills a concert hall of volume. If there were no ventilation, by how much would the temperature of the air rise over a period of 2.0h due to the metabolism of the people (70 W/person)? Assume the room is initially at 293 K.
(2)
Q = m*C*deltaT (?)
Convection equation (?)
(3)
I'm pretty stumped on this question, I tried to use Q=m*C*deltaT (by calculating the mass of air the room) but I don't think that's the right way to do it. I'm pretty sure this is a convection problem but I can't apply the convection equation because there's some missing values.
