Formula

The specific heat equation

Specific heat equationq = m × c × ΔT

Heat energy depends on the material mass, its specific heat capacity, and the amount of temperature change.

Worked example

Heating water example

Calculate the heat required to raise 100 grams of water by 10°C. The specific heat capacity of water is 4.18 J/(g·°C).

  1. Write the equation: q = m × c × ΔT
  2. Substitute the values: 100 × 4.18 × 10
  3. Multiply: 4,180
  4. The required heat energy is 4,180 J

Heating and cooling

Understand positive and negative values

Positive heat energy and temperature change normally represent heating. Negative heat energy and temperature change represent cooling.

When solving for mass or specific heat capacity, heat energy and temperature change must have matching signs so that the physical result remains positive.

Physics guidance

Common specific heat mistakes

  • Using final temperature instead of temperature change.
  • Mixing kilograms with a specific heat value based on grams.
  • Ignoring the sign of heat energy during cooling.
  • Confusing heat energy with temperature.
  • Rounding intermediate values too early.
