Question

Calculate the amount of heat energy to be supplied to convert 2 kg of ice at 0°c ,if latent heat of fusion is 80°cal/g°c.

Answer 1

Answer:

We know that latent heat required for melting of ice is

80

C

g

−

1

So,for

2

K

g

i.e

2000

g

,heat energy required will be

2000

⋅

80

=

160000

C

Explanation:

In this process heat energy will be required just to change the sate of matter i.e required latent heat will have to supplied.
