Question

How many kilocalories of heat does the operation of a 1200-W hair dryer produce each second?

Answer 1

1 kilocalorie per hour = 1.163W
1200/1.63 = ~1032 kilocalories per hour

As there are 3600 seconds in an hour:
1032/3600 = ~0.29 kilocalories produced per second

Answer 2

thank you sir! our physical science teacher is retarded, and never mentioned anything about watts or kilocalories and the relation between the two.

Answer 3
