Question

how much work when converted to heat can melt partly 2g ice at 0°C to 1.5g water at 0°C?​

Answer 1

Answer:

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

We know that latent heat required for melting of ice is

80

C

g

−

So,for

2

K

g

i.e

2000

g

,heat energy required will be

2000

⋅

80

=
