4 The student added more paperclips to one end of the magnet. The maximum number of paperclips the magnet could hold was 20 Each paper clip had a mass of 1.0 g gravitational field strength = 9.8 N/kg Calculate the maximum force the magnet can exert.

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.

thermal energy is the answer
