Question

What is the effect of rise in temperature on substance molecules

Answer 1

increase is kinetic energy

some times attraction of particles break down


some times change in state of matter

Answer 2

According to ‘kinetic theory’ of matter, all the matters are made up of ‘atoms and molecules’ that are moving constantly.  

Explanation:

• Whenever we applied a heat to the substance, the atoms and the molecules of the respective substance would vibrate faster.  

• Due to this faster vibration, the space between such atoms got increased.  

• This movement or motion and the space determine the state of the matter of the heated substance. This increased motion resulted in object expansion.
