An iron ball requires \(1000\ J\) of heat to raise its temperature by \(20\ °C\). Calculate the heat capacity of the ball.
 
From the given data,
 
Change in temperature (\(\Delta T\)) \(=\) \(20\ °C\)
 
Energy Supplied (\(Q\)) \(=\) \(1000\ J\)
 
We know that, Heat transfer (\(Q\)) is,
 
 
Formula to calculate heat capacity is,
 
 
Substitute the values,
 
Heat Capacity \(=\)
