Question

Particles in steam at 100 degree Celsius(373kelvin)have more energy than water at the same temperature.why

Answer 1

particles in steam at hundred degree Celsius and 373 degree Kelvin will have more energy than the water at same temperature because the steam would have observed the latent heat of vaporization which is equal to 540 calories

Answer 2

Explanation:

At 100°C, the water is present in two states: Liquid and gases.

$Liquid\rightleftharpoons Gas$

At this temperature, the water molecules get converted into vapor state. The energy of the vapor or steam particles is more than the water molecules although they are present at the same temperature because of the presence of Latent heat of vaporization.

Latent heat of vaporization is defined as the amount of energy required to convert a liquid into gas at constant temperature and pressure. This energy is hidden in the physical process.

Because of this heat, the particles of steam have more energy than water at same temperature.
