Question

how much heat
energy is required to convert 4 kg of water at hundred degree Celsius to water vapour​

Answer 1

Answer:

the change of the water from liquid phase at 100°c to vapour phase at the same temperature I.e. 100℃ is called latent heat of vapouration of water which is equal to 2260KJ/kG. this means, it requires 2260 kj of heat requird to chnge the phase of 1kg of water from liquid to vapour.
