Heat given to a body which raises its temperature by $1\ ^oC$ is
- AWater equivalent
- ✓Heat capacity
- CSpecific heat
- DTemperature gradient
✓
Answer
Correct option: B.
Heat capacity
b
The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius. The most commonly associated unit for specific heat is $1 .$ Specific heat is used to calculate the amount of heat absorbed when energy is added to a material or substance through an increase in temperature over a defined range.
