(c) the mass of the body
(d) the material of the body

उत्तर
(c) the mass of the body
(d) the material of the body
The bigger the body, the larger is its capacity to absorb heat. Therefore, the heat capacity of a body depends on the mass of the body. Also, different bodies have different heat capacities due to their material properties, i.e. due to their molecular structure, the heat capacity of a body depends on the material of the body.
