Question

4.When you heat a sample of gas, what happens to the particles that make up the gas? a) The particles move faster. (b) The particles break apart (c) The particles get smaller (d) The particles become more dense​

Answer 1

a) The particles move faster when a sample of gas is heated.

• On the heating sample of gas, the energy is given to the gas. As the gas is heated temperature increases and hence the speed.
• This energy is converted into kinetic energy. When there is an increase in kinetic energy, molecules move apart.
• The volume of the gas increases and attractive forces weaken between the molecules of gas.
