Final answer:
The amount of heat needed to increase the temperature of a substance is known as specific heat. It is a property that determines how much heat energy is required to raise the substance's temperature.
Step-by-step explanation:
The amount of heat needed to increase the temperature of 1 gram of a substance by 1 degree Celsius is known as specific heat. Specific heat is a property of a substance that determines how much heat energy is required to raise its temperature.
For example, if the specific heat of a substance is 4 J/g·°C, it means that 4 joules of heat energy are needed to raise the temperature of 1 gram of that substance by 1 degree Celsius.
Specific heat is reported in units of J/g·°C or cal/g·°C, depending on the system of measurement used.
