Boiling water is changing into steam, under this condition the specific heat of water in `"cals/g/"^(@)C` is:

A

1

B

zero

C

`oo`

D

`lt 1`

Text Solution

Verified by Experts

The correct Answer is:
C
Since there is zero change in temperature but heat is being absorbed
`therefore (Q)/(0)=prop`
`therefore` Correct choice is (c ).
