The molar heat capacity of water at constant pressure, C, is `75 JK^(-1) mol^(-1)`. When 1.0 kJ of heat is supplied to 100 g water which is free to expand, the increase in temperature of water is :

A

6.6K

B

1.2K

C

2.4K

D

4.8K

Text Solution

Verified by Experts

The correct Answer is:
C
Heat capacity of water per gram `= (75)/(18)= 4.17J`
Q= mst, 1000 `=100 xx 4.17 xx Delta T`
`Delta T= (1000)/(100 xx 4.17) = 2.4K`
