A thermally insulated vessel containing a gas whose molar mass is 32 g/mol and ratio of specific heats is 1.5 moves with a velocity of 100 m/s. Find the gas temperature increment (in °C) resulting from the sudden stoppage of the vessel. (Take R = 8 J/K-mol)
Options:
Answer:
B
Solution:
Kinetic energy per mole = 1/2(0.032)(100)2 = 160 J/mol. Cv = R/(γ - 1) = 2R = 16 J/K-mol. Δ T = 160/16 = 10°C. Matches (b).
