heater draws 1 Amp at 100 Volts over a period of 10 seconds. During that 10 seconds, 1 kg of
water flows through the water heater. The water enters the heater with a specific energy of 10
kJ/kg. What is the specific energy of the water when it exits the heater? (Assume the water heater
is well insulated.)
A) 9kJ
B) 10kJ
C) 11kJ
D) 12kJ
Solution
