Two identical rooms in a perfectly insulated house are connected by an open doorway. The temperature in the two rooms are maintained at different values. The room which contains more air molecules is :

Two identically sized rooms A and B are connected by an open door. If the room A is air conditioned such that its temperature is 4^(@) lesser than room B, which room has more air in it?

50 students sitting in the room of 5 xx 10 xx 3m^(3) dimensions. The air inside the room is at 27^(@)C and 1atm pressure. If each student loses 100 watt heat per second assuming the walls, ceiling floor, and all the material present inside the room is perfectly insulated as well as neglecting loss of air to the outside as the temperature is raised, how much rise in temperature will be noticed in 10min ? Given C_(P) = (7)/(2)R for air.
