Detailed explanation-1: -The change from the liquid state to the solid state is called freezing. As the liquid cools, it loses thermal energy. As a result, its particles slow down and come closer together. Attractive forces begin to trap particles, and the crystals of a solid begin to form.
Detailed explanation-2: -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. In a solid, the particles pack together as tightly as possible in a neat and ordered arrangement.
Detailed explanation-3: -If the temperature is increased the particles gain more kinetic energy or vibrate faster. This means that they move faster and take more space. If the temperature is decreased, it is the opposite. Particles move slower, because of less energy.
