3. if the particles in an object begin to move more
quickly, their average kinetic energy
the object's temperature
_and
a. increases, falls
b. decreases, rises
c. increases, rises
d. decreases, falls

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.
