Detailed explanation-1: -On heating, the particles will gain kinetic energy and break down the inter-particle force of attraction and start moving with great speed, which leads to changing their state from liquid to gas as well. Therefore, the given statement is true. Q. When the water is heated, particles of water move faster.
Detailed explanation-2: -energy will be transferred from the warmer object to the cooler one. The movement of thermal energy from a substance at a higher temperature to one at a lower temperature is called heat. When a substance is heated, it gains thermal energy. Therefore, its particles move faster and its temperature rises.
Detailed explanation-3: -When a system absorbs heat, the molecules start moving faster because kinetic energy increases, hence disorder increases. For the same amount of heat absorbed at lower temperature, the disorder is more than at higher temperature.
Detailed explanation-4: -Heating a substance makes its atoms and molecules move faster. This happens whether the substance is a solid, a liquid, or a gas.
