Question

latent heat of vaporization is a heat energy required to change 1 kg of a liquid to gas at atmospheric pressure at its melting point true or false​

Answer 1

The given statement is FALSE.

• The heat required to change one mole of liquid at its boiling point under standard atmospheric pressure is known as latent heat of vaporization

• In other words, it can be defined as - When a material in a liquid state(l) is given energy, it changes its phase from liquid (l) to vapor (v); the energy absorbed in this process is called the heat of vaporization(Lv).

• It is denoted as kg/mol or kJ/kg.

• It is a physical property of a substance.

Answer 2

Answer:

False

Explanation

Not at melting point but boiling point
