Heat Absorption Calculator


About Heat Absorption Calculator (Formula)

The Heat Absorption Calculator is a tool used to estimate the amount of heat absorbed or gained by a substance when its temperature changes. The formula for calculating heat absorption is as follows:

Heat Absorption = Mass × Specific Heat Capacity × Temperature Change


  • Heat Absorption: The amount of heat energy absorbed or gained by the substance.
  • Mass: The mass of the substance undergoing a temperature change, usually measured in kilograms (kg) or grams (g).
  • Specific Heat Capacity: The amount of heat energy required to raise the temperature of a unit mass of the substance by one degree Celsius (or Kelvin). It’s usually measured in joules per gram per degree Celsius (J/g°C) or joules per kilogram per degree Celsius (J/kg°C).
  • Temperature Change: The difference in temperature before and after the heat exchange, measured in degrees Celsius (°C) or Kelvin (K).

This calculation allows you to understand how much heat energy is absorbed or released as a substance’s temperature changes. The specific heat capacity is a crucial factor that varies depending on the substance, indicating how much energy is required to change the temperature of that substance.

Keep in mind that the formula provides an estimate, as it assumes that the specific heat capacity remains constant over the temperature range of interest. In reality, specific heat capacities can vary with temperature, particularly over wide ranges.

The Heat Absorption Calculator is commonly used in fields like thermodynamics, chemistry, and engineering to analyze heat transfer processes and design efficient cooling or heating systems.
