Heat Transfer Calculator

Find the heat needed to change a substance's temperature.

Mass

Specific heat (J/(kg·K))

Temperature change (K)

Heat (J) 251,160

Heat (kJ) 251.16

Formula: Q = m·c·ΔT

Step-by-step with your numbers:

1. Values used:

2. Mass = 2

3. Specific heat = 4,186 J/(kg·K)

4. Temperature change = 30 K

6. Heat = Mass x Specific heat x Temperature change = 2 x 4,186 x 30 = 251,160J

7. Heat = 251.16kJ

Did we solve your problem today?

The heat to warm or cool a substance depends on its mass, material and temperature change.

The math behind it

Q = m·c·ΔT. A positive ΔT means heat added; negative means heat removed.

2 kg of water warmed 30 K → about 251 kJ.

What is specific heat?

The energy to raise 1 kg of a material by 1 K.
