Study the given table and answer the following questions.


















Substances Sp. heat capacity
A 380 J/Kg0C
B 470 J/Kg0C
C 140 J/Kg0C

a. What is meant by the statement the specific heat capacity of B is 470 J/Kg0C?

b. If an equal amount of heat is given to an equal mass of these substances, which one will have the highest and which one will have the lowest temperature? Why?

c. If an equal mass of these substances at 1000C temperature are kept on a wax slab, which one will make the deepest hole on the wax slab? Why?

It means one kilogram mass of B requires 470J of heat to raise its temp. by 10C.

C will have the highest temperature because it has the lowest sp. heat capacity and B will have the lowest temperature because it has the highest sp. heat capacity.
From: sp. heat capacity  1/temperature.

B will make the deepest hole in the wax slab because it has more heat to release to the wax slab as it is with constant mass and temp. with the highest sp. heat capacity.
