Answer: a) ) kinetic energy of particles increases
b) inter particles distance increase.
Explanation: When wax is heated, the solid molecules change from solid phase to liquid phase and thus the molecules start moving faster as kinetic energy is directly proportional to temperature.
The molecules start moving faster and start moving away from each other decreasing the inter molecular forces thereby increasing the inter molecular distance between molecules.
