Question

30 kcal of heat is required to raise the temperature of 15 kg of substance from 20°c to 40°c then thermal capacity of the substance is ______

Answer 1

Q=msdeltaT
so 30000=15000xSx20
so on solving
S=0.1 cal/g/degree celcius

Answer 2

Answer:

1.5 Kcal per degree celsius

Explanation:

thermal capacity is asked in the question which is equivalent to heat capacity.

heat capacity = (amount of heat) / (rise in temperature)

= 30 Kcal / 20 degree celsius

= 1.5 Kcal per degree celsius
