Solution
- Latent heat of vaporisation of water is 22.5 × 105 J kg−1 which means that the heat requires to vaporise 1 kg of water is 22.5 × 105 J kg−1.
- Latent heat of vaporisation can be defined as the amount of heat needed for the conversion of 1 kg of liquid at its boiling point to gas at the same temperature.
- Latent heat of vaporisation of water is 22.5 × 105 J kg−1 which means that the heat requires to vaporise 1 kg of water is 22.5 × 105 J kg−1.
- Latent heat of vaporisation can be defined as the amount of heat needed for the conversion of 1 kg of liquid at its boiling point to gas at the same temperature.
