Heat supplied to a solid changes it into liquid. What is this change in phase called?
It has been observed that temperature remains constant till all solid melts into liquid. The heat supplied is used for changing a solid state into its liquid state by overcoming the particle-particle attraction force. The solid substance absorbs heat energy without showing any rise in temperature. This heat energy is called latent heat. The amount of heat required to convert a unit mass of a solid into its liquid state, without a change in temperature (i.e. at its melting point) is called the latent heat of fusion.EXPLAIN
Define boiling point of a liquid. At what temperature in the Kelvin scale does water boil ? Explain what happens when we supply heat energy to water till it changes its state. What is this heat energy called ?
