Specific heat of the substance is - 20 cal/ kg °C.
Heat capacity is also known as thermal capacity.
It is defined as "the amount of heat to be supplied to a given mass of a material to produce a unit change in its temperature."
Formula for the equation is -
Q = mc∆t
Q denotes heat energy, m denotes mass of the substance, c denotes specific heat capacity and t represents change in temperature.
Given values in question are -
Mass 3 kg,
Q = 600 cal of heat,
∆t = 10 °C
According to formula -
C= Q/m∆t
C = 600/3*10
C = 20 cal/ kg °C.
Thus, specific heat capacity of substance is 20 cal/ kg °C
