Answer:
31.96362 °C
Explanation:
= Mass of air in the room = 947 kg
= Mass of air entering the room = 62.4 kg
= Temperature in the room = 33.2°C
= Temperature air entering the room = 13.2°C
T = Equilibrium temperature
c = Specific heat of air = 1006 J/kg °C
In the case of thermal equilibrium we have the relation

The temperature of thermal equilibrium is 31.96362 °C
You would need to know how fast you threw the ball in the air once that then multiply the seeped and the time to get your answer<span />
