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.

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

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^(@)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
