Question

if x Calories of heat is supplied to 15 gram of water its temperature rises from 20 degree Celsius to 24 degrees celsius. if specific heat for water is 1 cal raise to -10 C raise to -1, then find the value of x

Answer 1

The value of x is 60 calories.

Explanation:

Specific heat capacity of water = 4.2 J/g℃

Heat capacity = 4.2 × 15  = 63 J/℃

Heat energy required = heat capacity × change in temperature

= 63 × 4

= 252 J

x = 60.2 calories

x = 60 calories

Hence the value of x is 60 calories.
