Question:Different substances require different amounts of ---(1)--- to change the STATE of the substance. This is known as the SPECIFIC ---(2)--- of a substance.1: energy per unit mass; 2: latent heat1: mass per unit energy; 2: heat capacity1: energy per unit mass; 2: heat capacity1: mass per unit energy; 2: latent heatAnswer:# Explanation:## Step 1To change the state of a substance (such as from solid to liquid or liquid to gas), energy is required. This energy is typically measured per unit mass of the substance.## Step 2The term "latent heat" refers to the amount of heat required to change the state of a substance without changing its temperature. This is different from "heat capacity," which refers to the amount of heat required to change the temperature of a substance.## Step 3Given the context of changing the state of a substance, the correct term for the energy required per unit mass is "energy per unit mass."## Step 4The specific term for the energy required to change the state of a substance is "latent heat."# Answer:1: energy per unit mass; 2: latent heat
