Heat Energy vs Mass
Formula
## Heat Transfer (Q = mcDeltaT) The heat energy needed to change the temperature of a substance depends on its mass, specific heat capacity, and temperature change. ### Formula **Q = m * c * DeltaT** where m is mass (kg), c is specific heat capacity (J/(kg·°C)), and DeltaT is the temperature change.
Exemplo Resolvido
Heating 1 kg of water from 20°C to 70°C (DeltaT = 50°C).
- 01Q = m * c * DeltaT
- 02Q = 1 * 4186 * 50
- 03Q = 209,300 J
- 04Q = 209.3 kJ
Perguntas Frequentes
What is specific heat capacity?
The amount of energy needed to raise 1 kg of a substance by 1°C. Water has one of the highest specific heats at 4186 J/(kg·°C).
Why does water take so long to heat up?
Water has a very high specific heat capacity, meaning it absorbs a large amount of energy per degree of temperature change.
Does this formula work for phase changes?
No. During a phase change (melting, boiling), temperature stays constant. Use heat of fusion or vaporization formulas instead.
