Answer 1

Explanation:

Latent heat of fusion is 336 J/g

Latent heat of vaporization is 2260 J/g

So, Heat released by 5g of steam to condense is Q

1

=5×10

−3

×2260×10

3

and, Heat absorbed by 5g of ice to melt is Q

2

=5×10

−3

×336×10

3

Heat require to increase temperature from 0

o

C to 100

o

C is Q

3

=mcΔT=5×10

−3

×4200×100=2100 J

As, Q

1

>Q

2

+Q

3

Hence, final temperature is at 100

o

C.

Partial steam will condense.
