Specific Heat Concept
Easyphysics
Specific heat is defined as heat required to raise temperature of unit mass by?
Select the correct option:
Solution
Incorrect! Answer:
1°C
- Definition: Specific heat capacity (c) is the quantity of heat required to raise the temperature of a unit mass (usually 1 kg or 1 g) of a substance by 1 unit of temperature.
- Units: Common units are J/(kg·K) or J/(kg·^\u00circC).
- Temperature Unit: Since a change of 1 K is identical to a change of 1∘C, '1 degree' is the defining unit.
- Equation: Q=mcΔT. If m=1 and ΔT=1, then Q=c.
