Two different samples have the same mass and temperature. Equal quantities of energy are absorbed as heat by each. Their final temperatures may be different because the samples have different
Correct answer: A. heat capacities
- A. heat capacities
- B. volume
- C. thermal conductivities
- D. co efficient of expensation
Explanation
Heat capacity is the measure of how much heat energy is required to raise the temperature of a substance by a certain amount. Different materials can have different heat capacities, meaning they can absorb different amounts of heat for the same increase in temperature.

About Molar Specific Heat of a Gas
Molar specific heat is the heat required to raise the temperature of one mole of a gas by one kelvin, expressed through Q = nCΔT. Questions compare the constant volume value Cv with the constant pressure value Cp, apply the ideal gas relation Cp − Cv = R, and identify how the thermodynamic process affects heat capacity.
