Question 194: Thermodynamics & KTG

Question

In an adiabatic process, which of the following statements is true?

Accepted Answer

Option B is correct.
Ã¢ÂÂ¢ In an adiabatic process no heat is exchanged, so
$$\delta Q = 0.$$
Ã¢ÂÂ¢ The (molar) heat capacity for any process is defined by
$$C = \frac{\delta Q}{n\,dT}\,. $$
Since $\delta Q=0$ even when $dT
eq0$, it follows that
$$C_{m adiabatic}=0\,. $$
All other statements are therefore false.

Answer

The internal energy of the gas decreases as the temperature increases

Answer

The molar heat capacity is zero

Answer

Work done by the gas equals the increase in internal energy

Answer

The molar heat capacity is infinite
