A 1500-W heater is designed to be plugged into a 120-Voutlet.

What current will flow through the heatingcoil when the heater is plugged in?

I = A

What is ,the resistance of the heater?

R = ohms

How long does it take to raise thetemperature of the air in a good-sized living room (3.00m*5.00m*8.00m)by 10.0 ? Note that the specific heat of air is 1006 J/(kg.c) and the density of air is 1.20kg/m3.

t= minutes
