Question

The amount of heat energy required to raise the temperature of $1kg$ of water through $1^{o}C$ is:

• A. Calorie.
• B. thermal capacity.
• C. Specific heat.
• D. Kilo calorie.

Answer 1

The correct option is D Kilo calorie.

Calorie - The amount of heat energy required to raise the temperature of $1g$ of water through $1^{o}C$ at a pressure of $1atm$.
Thermal capacity - The amount of heat energy required to produce a unit change of temperature in a unit mass of a substance.
Specific heat - The amount of heat energy required to raise the temperature of unit mass of a body through $1^{o}C$.
Kilo calorie - The amount of heat energy required to raise the temperature of $1kg$ of water through $1^{o}C$ at $1$atm.
