The particulate nature of matter explains that when a substance gets heated it particles gets energised and they move away from one another in a random manner, hence the correct options are
- The space between the particles is different with more space between particles in a gas
- The particles will have different kinetic energy
<em>What happens to particles when they are heated</em>
With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion.
With an increase in temperature, the particles gain kinetic energy and vibrate faster and more strongly
