The amount of heat energy required to in...

The amount of heat energy required to increase the temperature of 'X' g of water by `10 .^(@)C` is found to be 15 cal. Calculate 'X'.

A

0.5 g

B

15 g

C

1.5 g

D

7.5 g

Text Solution

Verified by Experts

The correct Answer is:
C
The specific heat of water is 1 `cal//g^(@)C`.
`therefore` Heat required for increasing `10^(@)C` temperature of x g water is 10 X cal.
`therefore` 10X = 15
`therefore` X = 1.5 g
