Of matter states that all particles of matter are in constant motion.

Answer

kinetic

Explanation

Matter is anything that occupies space and has mass. There are four states of matter, solids, liquids, gases and plasma. All this consist of small molecules that are in constant random motion. This is called kinetic theory of matter.

When these molecules are in motion they may collide. No energy is gained or lost during collision. The particle/molecules move in a constant linear motion.

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.
