Specific heat capacity is the amount of heat energy required to raise the temperature of a substance per unit of mass. The formula relating specific heat, mass, temperature change, and energy is: Q = m × c × ΔT

This calculator helps you find any of these values when you know the other three parameters.

About Specific Heat Capacity

Specific heat capacity is a measure of how much energy (in the form of heat) is needed to raise the temperature of a given mass of a substance by a certain amount.

Key Formula:

The fundamental equation relating heat energy, mass, specific heat capacity, and temperature change is:

  • Q = m × c × ΔT

Where:

  • Q = Heat energy transferred (joules, J)
  • m = Mass of the substance (kilograms, kg)
  • c = Specific heat capacity (joules per kilogram per kelvin, J/kg·K)
  • ΔT = Temperature change (kelvin or celsius, K or °C)
Common Specific Heat Capacities:
  • Water: 4,186 J/kg·K
  • Aluminium: 897 J/kg·K
  • Iron: 449 J/kg·K
  • Copper: 385 J/kg·K
  • Glass: ~840 J/kg·K
  • Concrete: ~880 J/kg·K
  • Wood (Oak): ~2,000 J/kg·K
  • Gold: 129 J/kg·K
  • Silver: 235 J/kg·K
  • Ice: 2,108 J/kg·K
  • Air: ~1,005 J/kg·K (at constant pressure)
Applications:
  • Thermal Engineering: Designing heating and cooling systems
  • Material Science: Characterising thermal properties of materials
  • Climate Control: Calculating heating and cooling requirements
  • Cooking: Understanding how different foods heat up
  • Calorimetry: Measuring heat transfer in chemical reactions
  • Insulation Design: Creating effective thermal barriers
Unit Conversions:
  • 1 joule (J) = 0.001 kilojoules (kJ)
  • 1 joule (J) = 0.239 calories (cal)
  • 1 calorie (cal) = 4.184 joules (J)
  • 1 kilocalorie (kcal) = 4,184 joules (J)
  • 1 BTU (British Thermal Unit) = 1,055 joules (J)
  • 1 kelvin (K) = 1 degree Celsius (°C) change
  • 1 kelvin (K) = 1.8 degrees Fahrenheit (°F) change

Understanding Specific Heat Capacity

Specific heat capacity measures how much energy is required to raise the temperature of a substance. In simple terms, it tells us how much heat energy is needed to warm up a certain amount of material. Each substance has its own specific heat value, which makes this concept essential for many scientific and practical applications.
