Which of the following is a factor in the heat capacity of an object?

Question

BlackTom AI · Accepted Answer

To evaluate what influences the heat capacity of an object, consider what heat capacity depends on and what each option represents.
Option 1: mass. Mass is directly related to heat capacity because more mass means more material that can store thermal energy; for a given temperature change, a larger object requires more heat to raise its temperature by the same amount, increasing the heat capacity.
Option 2: enthalpy. Enthalpy is a state function describing the total heat content at constant pressure, not a property that scales with the capacity to store additional heat for temperature changes in a simple manner. It reflects energy content rather than the ability to absorb heat per degree of temperature change, so it is not a direct factor in the heat capacity of an isolated object.
Option 3: shape. The geometric shape of an object does not inherently change how much energy is needed to change its temperature by a given amount. For the same mass and material, a slender rod or a bulky sphere tends to have similar heat capacity, so shape is not a fundamental factor.
Option 4: potential energy. While potential energy is a form of energy, heat capacity concerns how much heat is required to raise temperature, not the static potential energy in a gravitational or other field. Therefore, potential energy does not directly set the heat capacity of the object.
In summary, among the given choices, mass stands out as the primary factor that scales the amount of heat required for a given temperature increase, while the other options describe other energy concepts or do not influence heat capacity in a straightforward way.
