Does the specific heat capaciry change with chanhe from soild to liquid
Answers
When a substance changes from one state to another, the temperature remains constant. For example, when heat energy is added to ice at its melting point ( 0^{\circ}C ), it changes into the same mass of water at 0^{\circ}C .
A solid substance at its melting point has less energy than the same mass of the substance when it is a liquid at the same temperature.
To change a solid into a liquid, or a liquid into a gas, requires heat energy. This heat energy allows the change of state to happen, and the temperature remains constant during the process.
The amount of heat energy required to change the state of a substance depends on the mass and type of substance, and whether the change is solid to liquid or liquid to gas.
This heat energy is known as latent heat energy (symbol ‘ l’).
The amount of heat energy required to change the state of 1 kg of a substance at its melting point is called the specific latent heat of the substance.
