The image above represents quantity of heat. To calculate quantity of heat, three essential parameters are needed and these parameters are Mass of the Stock (m), Specific Heat of Stock (Cp) and Change in Temperature (ΔT).
The formula for calculating quantity of heat:
Q = mCpΔT
Where:
Q = Quantity of Heat
m = Mass of the Stock
Cp = Specific Heat of Stock
ΔT = Change in Temperature
Let’s solve an example;
Find the quantity of heat when the mass of the stock is 18, the specific heat of stock is 10 and the change in temperature is 12.
This implies that;
m = Mass of the Stock = 18
Cp = Specific Heat of Stock = 10
ΔT = Change in Temperature = 12
Q = mCpΔT
So, Q = 18(10)(12)
Q = 2160
Therefore, the quantity of heat is 2160 J/kg K.
Calculating the Mass of the Stock when the Quantity of Heat, the Specific Heat of Stock and the Change in Temperature are Given
m = Q / Cp x ΔT
Where;
m = Mass of the Stock
Q = Quantity of Heat
Cp = Specific Heat of Stock
ΔT = Change in Temperature
Let’s solve an example;
Find the mass of the stock when the quantity of heat is 15, the specific heat of stock is 3 and the change in temperature is 4.
This implies that;

Q = Quantity of Heat = 15
Cp = Specific Heat of Stock = 3
ΔT = Change in Temperature = 4
m = Q / Cp x ΔT
That is, m = 15 / 3 x 4
m = 15 / 12
m = 1.25
Therefore, the mass of the stock is 1.25 Kg.

Calculating the Specific Heat of Stock when the Quantity of Heat, the Mass of the Stock and the Change in Temperature are Given
Cp = Q / m x ΔT
Where;
Cp = Specific Heat of Stock
Q = Quantity of Heat
m = Mass of the Stock
ΔT = Change in Temperature
Let’s solve an example;
Given that the quantity of heat is 10, the mass of the stock is 2 and the change in temperature is 5.
This implies that;
Q = Quantity of Heat = 10
m = Mass of the Stock = 2
ΔT = Change in Temperature = 5
Cp = Q / m x ΔT
Cp = 10 / 2 x 5
That is, Cp = 10 / 10
Cp = 1
Therefore, the specific heat of stock is 1 J/Kg.

Calculating the Change in Temperature when the Quantity of Heat, the Mass of the Stock and the Specific Heat of Stock are Given
ΔT = Q / m x Cp
Where;
ΔT = Change in Temperature
Q = Quantity of Heat
m = Mass of the Stock
Cp = Specific Heat of Stock
Let’s solve an example;
Find the change in temperature when the quantity of heat is 40, the mass of the stock is 2 and the specific heat of stock is 10.
This implies that;
Q = Quantity of Heat = 40
m = Mass of the Stock = 2
Cp = Specific Heat of Stock = 10
ΔT = Q / m x Cp
So, ΔT = 40 / 2 x 10
ΔT = 40 / 20
ΔT = 2
Therefore, the change in temperature is 2 K.
