Final answer:
The amount of heat required to raise the temperature of a sample of water is referred to as specific heat (C).
Step-by-step explanation:
The amount of heat required to raise the temperature of a sample of water is referred to as specific heat (C). Specific heat is defined as the amount of heat needed to raise the temperature of 1 gram of a substance by 1°C. Water has a high specific heat compared to most other substances, which means it requires more energy to increase its temperature.
