Question

Water as ice has cooling effect but water as steam may cause severe burns.why?

Answer 1

steam has more energy burns affect , at this temp. latent heat of vaporisation. stean more severe burns produced by severe meters, . this is your answer

Answer 2

Water shows a property of absorbing and releasing a fixed amount of energy just as any other liquid.

This fixed amount of energy is known as latent heat

It is of two types

Latent heat of fusion

AND

latent heat of vaporisation

During conversion of ice into water , ice absorbs some amount of energy from the surrounding for conversion of state known as latent heat if fusion..we can't measure this energy but it exists.

So when heat is absorbed surrounding becomes cool

Similarly

Between steam and water

Steam is more powerful as it has 336 joules of energy ( value of latent heat of vaporisation for water) than water and hence causes more severe burns

Hope u got it

Thank u★★★
