Question

explain latent heat

Answer 1

LATENT HEAT :
During the process of melting of vaporization the temperature remains constant the amount of heat required to melt a solid or vaporize a liquid of mass M is given by
Q= mL
where L is called latent heat during melting of solid into liquid L is called latent heat of fusion and during vaporization of liquid L is called latent heat of vaporization when a vapour condenses or liquid solid sides heat is released to the surroundings

some important terms to know more about latent heat ;

⏩MELTING POINT:
the temperature at which both the solid and liquid state of the substances coexist in thermal equilibrium during the change of state from solid to liquid
It depends on pressure

⏩BOILING POINT:
the temperature at which the liquid and the vapour states of the substances coexist in thermal equilibrium is called its boiling point

⏩THE TRIPLE POINT OF WATER :

the triple point is a state in which ice,water and water vapour can stay together in thermal equilibrium its value is 273.16 Kelvin it is selected as the standard fixed point temperature for the calibration of thermometer
