Final answer:
The symbol that represents the dryer heat thermostat is symbol c, which stands for specific heat. Specific heat is the amount of heat required to change the temperature of a substance.
Step-by-step explanation:
The symbol that represents the dryer heat thermostat is symbol c. In physics, the symbol c stands for the specific heat of a substance. Specific heat is the amount of heat required to change the temperature of 1.00 kg of mass by 1.00°C. The specific heat depends on the material and phase of the substance, and it is measured in J/(kg·K) or J/(kg·°C).
