Question

How much heat energy is produced by 0.5 wh of electrical energy

Answer 1

0.5 Wh of electrical energy is equal to 1.8 kJ of heat energy.

Step-by-step explanation:

0.5 Wh of electrical energy is equivalent to 16.2 kJ of heat energy. To convert from Wh to kJ, we use the fact that 1 Wh is equal to 3,600 J. So, by multiplying 0.5 Wh by 3,600 J, we get 1,800 J. To convert from J to kJ, we divide by 1,000, which gives us 1.8 kJ. Therefore, 0.5 Wh of electrical energy is equal to 1.8 kJ of heat energy.

Answer 2

1 hour = 3,600 seconds

1 watt-hour = 3,600 watt-seconds

0.5 watt-hour = 1,800 watt-seconds

= 1,800 joules of energy, in ANY form.
