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

Respuesta :

the answer is option D

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.
