Question

Heat capacity of a body is:

• A. the energy needed to melt the body without the change in its temperature
• B. the energy needed to raise the temperature of the body by 1°C
• C. the increase in the volume of the body when its temperature increases by 1°C
• D. the total amount of internal energy that is constant.

Answer 1

Answer:

B. the energy needed to raise the temperature of the body by 1°C

Heat capacity (C) is defined as:

The amount of heat energy required to raise the temperature of a body by 1 degree Celsius (or Kelvin).

Mathematically, it's represented as:

C = Q / ΔT

Where:

• C = heat capacity

• Q = amount of heat energy

• ΔT = change in temperature (usually 1°C or 1 K)
