The rise in temperature is 0.49°c
<h3>What is specific heat capacity?</h3>
The quantity of heat energy needed to raise a substance's temperature per unit of mass is known as specific heat capacity. A material's specific heat capacity is a physical characteristic. Since its value is inversely correlated with the size of the system under study, it is also an illustration of an extended feature.
<h3>what is law of conservation of energy?</h3>
Energy can only be transformed from one form to another. It cannot be created or destroyed
<h3>How will this question be solved?</h3>
From law of conservation of energy we know,
Potential energy of the block= cmΔT
mgh= cmΔT
m×9.8×20= 400×m×ΔT
196=400ΔT
ΔT=0.49°C
