Question

Numerical Problems.

An iron ball requires 1000 J of heat to raise its temperature by 20°C. Calculate the heat capacity of the ball.

Sum

Solution

Heat capacity C’ = `"Q"/"ΔT"`
Here, A = 1000 J

T = 20°C – 0°C = 20°C = 20 k

C= `1000/20` = 50 JK-1

Here, A = 1000 J

T = 20°C – 0°C = 20°C = 20 k
