Question

The required heat energy to convert 500ml
of water completely to vapour is
1) 27 K.cal 2) 270 K.cal
3) 54 K.cal
4) 540 K.cal​

Answer 1

Answer:

Amount of Heat energy Required = Mass × Latent heat of Vaporization. Latent heat of Vaporization of Water = 2260 J/kg. Thus, the amount of Heat energy required to convert Water at 100° C into vapor is 11300 Joules

Answer 2

Answer:

2) 270k.cal

Explanation:

the amount of heat energy required is 270k.cal
