How it works
Heat energy Q = mass × specific heat capacity × temperature change. Phase-change energy is excluded.
Input definitions
- Mass (kg)
- Enter the value in the labeled unit.
- Specific heat capacity (J/kg·K)
- Enter the value in the labeled unit.
- Temperature change (K or °C interval)
- Enter the value in the labeled unit.
A worked example
- Mass (kg)
- 2
- Specific heat capacity (J/kg·K)
- 4184
- Temperature change (K or °C interval)
- 10

Common questions
Can the temperature change be negative?
Yes. Negative Q represents heat leaving the material under this sign convention. The formula assumes constant specific heat.
How does Sensible heat energy work?
Heat energy Q = mass × specific heat capacity × temperature change. Phase-change energy is excluded.
What should I check before using Sensible heat energy?
Ideal educational model in the stated SI units. Real equipment, structural design and safety decisions need appropriate professional analysis; losses are excluded unless entered.
