How many Joules of heat are generated by a heater that outputs 500 W for 10 minutes?

A. 300 J
B. 500 J
C. 3000 J
D. 5000 J

Answer :

Final answer:

The heater generates 300,000 joules of heat when it operates at 500 watts for 10 minutes (option c).

Explanation:

To calculate the heat generated by the heater, we'll use the formula that relates power (P), time (t), and energy (E):

E = P × t

Given that the power of the heater is 500 watts (W) and the time is 10 minutes, we first need to convert minutes into seconds since the standard unit for time in this context is the second (s), and power is in watts, which is joules per second.

10 minutes × 60 seconds/minute = 600 seconds

Now we can calculate the energy:

E = 500 W × 600 s = 300,000 J

Therefore, the heater generates 300,000 joules of heat.
