Heat Transfer Formula

Heat transfer is the energy transferred due to temperature differences. It depends on mass, specific heat capacity, and temperature change.
Q = mc?T

Variables:

QHeat transfer (J)
mMass (kg)
cSpecific heat capacity (J/kg*K)
?TTemperature change (K)

Example

Heat Transfer Example

Inputs:

Mass:1 kg
Specific Heat:4186 J/kg*K
Temperature Change:10 K
Time:1 s

Steps:

  1. 1.Calculate heat transfer: Q = mcDeltaT = 1 x 4186 x 10 = 41,860 J
  2. 2.Calculate power: P = Q/t = 41,860/1 = 41,860 W
  3. 3.This represents heating 1 kg of water by 10 C
  4. 4.Water has a high specific heat capacity of 4186 J/kg*K
Result:
Heat Transfer: 41,860J | Power: 41,860W | Energy: 41,860J

Frequently Asked Questions

What is heat transfer?

Heat transfer is the energy transferred between objects due to temperature differences. It occurs through conduction, convection, or radiation.

What is specific heat capacity?

Specific heat capacity is the amount of heat required to raise the temperature of 1 kg of a substance by 1 Kelvin. Water has a high specific heat capacity of 4186 J/kg*K.
