Thermodynamics MCQ with Answers

131) The general law of expansion or compression is pvⁿ = C, The process is said to be hyperbolic, if n is equal to

Answer is:

1

132) The state of a substance whose evaporation from its liquid state is partial, is known as steam.

Answer is:

Disagree

Explanation:

A perfect gas (or an ideal gas) may be defined as a state of a substance, whose evaporation from its liquid state is complete. It may be noted that if its evaporation is partial, the substance is called vapor. A vapor contains some particles of liquid in suspension.

133) The value of universal gas constant is same for all gases.

Answer is:

Yes

134) The numerical value of the thermal capacity and the water equivalent of the substance are the same.

Answer is:

Agree

135) The area under the temperature-entropy curve (i. e. T - s curve) of any thermodynamic process represents the workdone during the process.
