Question

Effect of temperature on change of state

Answer 1

Effect of temperature on the states of matter

On heating a solid substance, the kinetic energy of its constituent particles increases. As a result, the particles start vibrating with greater speed. This extra energy helps the particles to overcome the inter-particle force of attraction. Soon, they leave their positions and start moving more freely. Consequently, the substance melts. The change of solid state into liquid state is known as fusion. The minimum temperature at which a substance starts melting and becomes a liquid at atmospheric pressure is known as its melting point.

$Question$ :-

1. Effect of change in temperature?

$Answer$ :-

➝The temperature effect on heating a solid varies depending on the nature of the solid and the conditions required in bringing the change.

• On increasing the temperature of solids, the kinetic energy of the particle increases which overcomes the forces of attraction between the particles thereby solid melts and is converted to a liquid.
• The temperature at which a solid melts to become a liquid at the atmospheric pressure is called its melting point.
• The melting point of ice is 273.16 k.
• The process of melting that is change of solid state into liquid state is known as fusion.
