Question

Which contains more heat 1 kg of water at 100c or 1 kg of steam at 100c give reason?

Answer 1

Answer:

1 kg of steam contains more heat than 1 kg of water because to convert water into steam, the heat used is more than the actual boiling point. We call this extra heat as latent heat. Thus, water contains its own heat but steam contains its own heat as well as the latent heat.

Answer 2

Explanation:

1 kg of steam contains more heat energy than 1 kg of liquid water.

This is a rather strange concept to think of, but besides kinetic energy (which affects temperature), matter also has potential energy depending on what state it’s in.

To boil water, you need to put energy in to heat it to around 100°C.
