Molar specific heat of a substance denoted by symbol C does not depend...
The symbol c stands for specific heat and depends on the material and phase. The specific heat is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00degreeC. The specific heat c is a property of the substance; its SI unit is J/(kg⋅K) or J/(kg⋅C).

The molar specific heat of a substance, denoted by symbol C, refers to the amount of heat energy required to raise the temperature of one mole of the substance by one degree Celsius (or Kelvin). It is a property of the substance and is independent of the condition under which the heat is supplied, the temperature of the substance, and the amount of the substance. However, it does depend on the nature of the substance itself.
Condition under which heat is supplied:
The molar specific heat of a substance does not depend on the condition under which the heat is supplied. Whether the heat is supplied at a constant pressure (Cp) or a constant volume (Cv), the molar specific heat remains the same. Cp and Cv are specific heat capacities at constant pressure and constant volume, respectively, and they can differ for a substance. However, the molar specific heat, which is an intrinsic property of the substance, remains constant regardless of the conditions.
Temperature of the substance:
The molar specific heat of a substance is independent of the temperature at which the heat is supplied. It remains the same whether the substance is at a low temperature or a high temperature. This is because the molar specific heat is a property of the substance itself and does not change with temperature.
Amount of the substance:
The molar specific heat of a substance is also independent of the amount of the substance. Whether one mole or multiple moles of the substance are considered, the molar specific heat remains constant. This is because the molar specific heat is defined as the heat required to raise the temperature of one mole of the substance.
Nature of the substance:
The molar specific heat of a substance does depend on the nature of the substance. Different substances have different molar specific heat values due to variations in their molecular structures and bonding. For example, the molar specific heat of water is different from that of copper because their molecular structures and bonding are different.
In conclusion, the molar specific heat of a substance, denoted by symbol C, does not depend on the condition under which heat is supplied, the temperature of the substance, or the amount of the substance. However, it does depend on the nature of the substance itself.
