Expert Answer:

The amount of heat gained or lost by a body depends upon,
i. mass of body
ii. Nature of substance 
iii. Rise in temperature of body
 
Let the amount of heat gained or lost be Q, the mass of the body is m, and the rise in temperature is Δt
 
Thus, 
Q α mΔt
 
Thus,
Q = constant × m × Δt
Q = s × m × Δt
where, s is the proportionality constant known as specific heat of the substance
