Question

When you heat a sample of gas, what happens to the particles that make up the gas?

  1. The particles move faster 
  2. The particles get broken 
  3. The particles size gets smaller
  4. The particles become more denser

hintHint:

Every form of matter in this universe is composed of tiny particles called atoms which further have subatomic particles.

The correct answer is: The particles move faster


    • When we heat a sample of gas, the particles that make up the gas start to move faster. 
    • All matter in this universe is composed of tiny particles. These particles are known as atoms that further consist of subatomic particles like electrons, protons, and neutrons. 
    • The electrons have the tendency to jump into higher energy levels, getting excited by external stimuli. Thus, when the gas is heated, the particles gain this heat energy, get excited, and vibrate. This results in the particles moving quickly and away from each other. 

    This phenomenon is used by various industries to heat up the gas.
