[#146] Kinetic theory of gases assumes that the collisions between the molecules are
Correct Answer
(A) Perfectly elastic
[#147] According to Kelvin-Planck's statement, a perpetual motion of the __________ is impossible.
Correct Answer
(B) Second kind
[#148] The efficiency of Stirling cycle is __________ Carnot cycle.
Correct Answer
(C) Equal to
Explanation
Solution: The Stirling cycle is a type of thermodynamic cycle that operates between two temperature limits, similar to the Carnot cycle. In theory, the efficiency of the Stirling cycle is equal to that of the Carnot cycle, as both are reversible cycles and achieve the maximum possible efficiency for a given temperature difference. This efficiency is determined by the Carnot efficiency, which depends solely on the temperature difference between the heat source and the heat sink.
