What is the definition of specific heat capacity?

Specific heat capacity tells you how much energy is needed to raise the temperature of a substance, per unit mass, for a given temperature change. It is defined as the energy required to raise the temperature of one gram of a substance by one degree Celsius (1°C). That’s why this option is the best: it directly describes the amount of energy needed per gram for a 1°C increase. The other ideas describe different concepts: energy to evaporate a substance is latent heat of vaporization, not specific heat. Energy stored refers to the total energy content or internal energy, not how much energy is needed for a small temperature rise per gram. The rate of heat transfer talks about how fast energy moves, not the amount required to change temperature. Water, for example, has a high specific heat capacity, so it takes a relatively large amount of energy to raise its temperature by 1°C per gram.
