A. Specific heat capacities of three different substances are given below: Substances
Specific heat capacity
A
910 J/kg °C
B
380 J/kg °C
C
470 J/Kg °C
1.What do you mean by specific heat capacity of A is 910 J/kg °C?
2.Which above given substance will gain least temperature while heating equal mass
of all the three substances supplied with equal amount of heat? Give reason.
3.Which one will go down least in depth while keeping equal mass at the three
substances heated for the same temperature of 100 °C and kept on a wax slab, why?

1)substance A will require 910 J of heat to increase the temperature by 10°C.

2) Substance B

3) Substance A

Explanation:

1) The meaning of the statement: "specific heat capacity of A is 910 J/kg °C" is that 1 kg of substance A will require 910 J of heat to increase the temperature by 10°C.

2) While heating equal mass of all the three substances supplied with equal amount of heat, Substance B will gain more temperature due to the fact that substances of lesser specific heat capacity always tend to gain or loose heat within a short period of time.

3) While keeping equal mass at the three substances heated for the same temperature of 100°C and kept on a wax slab, substance A will go down more in depth due to the fact that heat is preserved for a longer period of time for substances that have higher specific heat capacity.
