Question

15.   Which of the following is accurate when discussing specific heat?

  A. Specific heat values for solids will never vary for different ranges of temperature.
  B. The specific heat of a gas can be measured at constant volume only.
  C. Specific heat values for liquids will never vary for different ranges of temperature.
  D. The specific heat of a gas may be measured at constant pressure

Answer 1

the answer is option D

Answer 2

Answer;

D. The specific heat of a gas may be measured at constant pressure

Explanation;

• The specific heat is the amount of heat per unit mass required to raise the temperature of a substance by one degree Celsius. Therefore; it is the amount of heat required to raise 1 kg of the material by 1°C.
• The specific heat measures how much energy is stored in a heated object. Specific heat of a gas may be measured at constant pressure.
