the temp of a room is 10c in 1 hr the room is heated to 20c by 1kw heater.how much heat is deliverd to room?
b)what is the thermal capacity of the room?
c)does all this heat goes to the room?
Convert one kilowatt running for 1 hr to kW-hrs and then to joules of energy made in one hour and that is answer to a)
1 kW = 2.7778×10^7 Joules of heat energy
———————————————————————-
b) I’m not sure you can determine the thermal capacity of the room. I think the thermal capacity is unlimited…you can keep heating the air until it turns to plasma…
—————————————————————-
1 thermochemical calorie = 4.184 J
It takes 30.2 J/mole of air to raise the room temperature one degree centigrade.
Room was raised 10C in one hour..
If this was an electric heater then all the heat produced goes to the room,100%
