What is the effect of temperature on particles of matter?

Answer 1

Temperature is a measure of the micro-kinetic energy of matter, the vibrational energy of the atoms or molecules making up the matter. The more energetic the vibration the higher the temperature.

Answer 2

Increasing temperature causes particles to gain energy and move more rapidly. This can lead to an increase in collisions between particles, resulting in higher kinetic energy and expansion of the substance. Conversely, decreasing temperature causes particles to lose energy, leading to reduced movement and a decrease in volume.
