Topic: Thermodynamics
The quantity of heat required to change the temperature of 1 gm of ice cream -6 °C to -5 °C is known as
- A. Latent heat of freezing
- B. Freezing heat
- C. Heat of vaporization
- D. Specific heat
Answer: D. Specific heat
Explanation: Specific heat is defined as the amount of thermal energy needed to raise the temperature of 1 gram of a substance by 1 degree Celsius. Therefore, raising ice cream from -6 °C to -5 °C represents its specific heat.
