The substance having highest specific latent heat of vaporisation is :
The substance having highest specific latent heat of vaporisation is :
Open in App
Solution
The correct option is D water
The specific latent heat of vaporization is the quantity of heat energy needed to vaporize 1 kg of a substance without changing its temperature.
Water exhibits anomalous behaviour. From 0 C to 4 C it contracts as heated. It also expands when it freezes. The expansion results in a decrease in density, allowing ice to float on water. Also, water has a high specific heat capacity compared to other liquids.
