`0.93` watt - hour of energy is supplied to a block of ice weighing 10 gm. It is found that

A

Half of the block melts

B

The entire block melts and the water attains a temperature of `4^(@)C`

C

The entire block just melts

D

The block remains unchanged

Text Solution

Verified by Experts

The correct Answer is:
C
Energy supplied `=0.93xx3600` joules
=3348 joules
Heat required to melt 10 g of ice `=10xx80xx4.18= 3344` joules
Hence block of ice just melts
