Question

what is kinetic energy? what is kinetic energy best at: SOLID, LIQUID or GASEOUS state and why?

Answer 1

The kinetic energy of an object is the energy that it possesses due to its motion.

Gas

Increase in temperature increases the speed in which the gas molecules move.

Answer 2

Answer:

the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.

The amount of kinetic energy in a substance is related to its phase. Gaseshave more kinetic energy than liquids. Liquids have more kinetic energy than solids. When a substance increases in temperature, heat is being added, and its particles are gaining kinetic energy.
