Enter the energy in Btu, the mass in pounds, and the specific heat in Btu/lb°F into the calculator to determine the temperature change in degrees Fahrenheit.
Btu to Temperature Change Formula
The following formula is used to calculate the temperature change when energy is added to or removed from a substance.
ΔT = Q / (m * c)
Variables:
- ΔT is the temperature change (°F)
- Q is the energy in Btu
- m is the mass of the substance in pounds (lb)
- c is the specific heat of the substance in Btu/lb°F
To calculate the temperature change, divide the energy in Btu by the product of the mass in pounds and the specific heat in Btu/lb°F.
What is Specific Heat?
Specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius. The specific heat of a substance is a measure of how much energy the substance can absorb before its temperature rises. Different substances have different specific heats, which can affect how they respond to heat energy.
How to Calculate Temperature Change?
The following steps outline how to calculate the temperature change using the Btu to Temperature Change Calculator.
- First, determine the energy in Btu (Q).
- Next, determine the mass of the substance in pounds (m).
- Next, determine the specific heat of the substance in Btu/lb°F (c).
- Next, gather the formula from above = ΔT = Q / (m * c).
- Finally, calculate the temperature change (ΔT) in degrees Fahrenheit.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
Energy in Btu (Q) = 150 Btu
Mass in pounds (m) = 5 lb
Specific heat in Btu/lb°F (c) = 0.2 Btu/lb°F
