Question

(a) Define the term 'latent heat of vaporisation' of a liquid. What is the value of the latent heat of vaporisation of water ?
(b) Draw a labelled diagram of the experimental set-up to study the latent heat of vaporisation of water.

Answer 1

Answer:

latent heat of vapourisation = the amount of heat energy required to change 1 kg of water into vapour.... ......

Hope it helps you atleast a little bit.....

Answer 2

Answer:

Latent heat of vaporization is a physical property of a substance. It is defined as the heat required to change one mole of liquid at its boiling point under standard atmospheric pressure. ... The heat of vaporization of water is about 2,260 kJ/kg, which is equal to 40.8 kJ/mol.
