The specefic heat of a gas in an isothermal process is:

Correct answer: A. Infinity

  • A. Infinity
  • B. Negative
  • C. Zero
  • D. Remains constant

Explanation

Given the process is isothermal which means it's temperature won't increase i.e. ∆T = 0. Hence, Cp =n/ΔTΔQ = n/0×∆Q = infinity Therefore specific heat will be infinity, as it is defined as heat supplied per unit increase in temperature.

About Molar Specific Heat of a Gas

Molar specific heat is the heat required to raise the temperature of one mole of a gas by one kelvin, expressed through Q = nCΔT. Questions compare the constant volume value Cv with the constant pressure value Cp, apply the ideal gas relation Cp − Cv = R, and identify how the thermodynamic process affects heat capacity.
