Detailed explanation-1: -The amount of heat gained or lost by a sample (q) can be calculated using the equation q = mcT, where m is the mass of the sample, c is the specific heat, and T is the temperature change.
Detailed explanation-2: -Q = m•C•T where Q is the quantity of heat transferred to or from the object, m is the mass of the object, C is the specific heat capacity of the material the object is composed of, and T is the resulting temperature change of the object.
Detailed explanation-3: -Therefore, heat energy is dimensionally represented as [M1 L2 T-2].
Detailed explanation-4: -This equation tells about amount of heat change per unit change of temperature experienced by a body of unit mass. So, the units for ‘q’ are Joules in mks system.
