Which term describes the amount of heat required to raise the temperature of 1 g of a substance by 1 °C or 1 K?

• A. Latent heat
• B. Enthalpy
• C. Molar heat capacity
• D. Specific heat capacity

Answer: (D)

Verified step by step guidance

1. Understand the definition of the terms given in the problem: Latent heat, Enthalpy, Molar heat capacity, and Specific heat capacity.
2. Latent heat refers to the heat required for a phase change of a substance without changing its temperature, such as melting or boiling.
3. Enthalpy is a thermodynamic quantity representing the total heat content of a system, often used in reactions and phase changes but not specific to per gram or per degree changes.
4. Molar heat capacity is the amount of heat required to raise the temperature of one mole of a substance by 1 °C or 1 K.
5. Specific heat capacity is defined as the amount of heat required to raise the temperature of 1 gram of a substance by 1 °C or 1 K, which matches the description in the problem.
