Question

On what factors does the heat required by an object to increase its temperature depends?

Accepted Answer

The amount of thermal energy required to increase the temperature of a substance by $1 {}^{\circ}C$ is called the specific heat capacity of the material, it depends on the following factors -

a) Mass of the object $(m)$ , larger the mass of an object, higher the required thermal energy for increasing the temperature by a fixed amount.

b) Extent of the change in temperature $(t)$ , higher the increase in temperature, larger is the thermal energy needed.

c) Nature of the material of the object, to increase the temperature by the same amount, objects of different material, with equal mass, require a different amount of thermal energy. This energy needed depends upon the nature of the material. Metals and oil heat up faster in comparison to water. It means that to increase the temperature of these objects by the same amount we require less thermal energy than for water.
