Question

How much energy for water at 100 to steam at 100 c?

Answer 1

Answer:

A sample of 0.1 g of water at 100°C and normal pressure (1.013 x 105 Nm-2) requires 54 cal of heat energy to convert to steam at 100°C. If the volume of the steam produced is 167.1 cc, the change in internal energy of th

Answer 2

Answer:

Latent heat of vaporisation of water is 22.5 × 105 J/kg. It means that 22.5 × 105 J of heat is required to change 1 kg of water at 100°C into steam at the same temperature. It means that 1 kg of steam at 100°C has 22.5 × 105 J more energy than 1 kg of water at the same temperature.
