The amount of heat energy required to increase the temperature of 'X'

1.	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'.
Answer» 0.5 g 15 g 1.5 g 7.5 g Solution :The SPECIFIC HEAT of water is 1 cal `g^(-1) .^(@)C^(-1)`. Therefore the amount of heat required is 1.5 cal for 15 for `10^(@)C` raise in temperature.
