how do particle of matter posses kinetic energy ? Is kinetic energy affected by heat
Answers
Ur answer is here mate.
Kinetic theory of matter: All matter is made up of atoms and molecules that are constantly moving.
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.
Solid at Different Temperatures
Mass of the object remains the same, however. Solids, liquids and gases all expand when heat is added. When heat leaves all substances, the molecules vibrate slower. The atoms can get closer which results in the matter contracting. Again, the mass is not changed.

Thanks for giving me a wonderful chance to help you.
- When there's a sudden increasing in temperature of an solid – The particles of matter posses kinetic energy.
- When theres increase of temperature, kinetic energy of the particles increase the particles start vibrating with greater speed.
- The particles are having spaces between them when the particles start vibrating and the particles move more freely.
- When there's no fixed positions for particles, they move freely and this case one of the point from converting solid particles into liquid.
