Answer: specific heat capacity.
- A specific heat capacity
- B the latent heat
- C the thermal conductivity
- D the emissivity
Correct answer: A. specific heat capacity
Explanation: Specific heat capacity is the heat per unit mass per unit temperature rise.
During a phase change (melting or boiling), temperature stays constant while heat is absorbed entirely as latent heat (Q=mL); temperature only rises again once the substance is fully in its new phase.
Concept context
Temperature scales, thermal expansion, calorimetry, and the three modes of heat transfer including radiation laws.
