Question

A vessel containing one gram-mole of oxygen is enclosed in a thermally insulated vessel. The vessel is moved with a constant speed v 0 ​ and then suddenly stopped. The process results in a rise in the temperature of the gas by 1 ∘ C. Calculate the speed v 0 ​ .

TestHub · Accepted Answer

The kinetic energy of the gas goes into internal energy: 2 1 ​ M v 0 2 ​ = C v ​ Δ T = 2 5 ​ R × 1 = 20.79 J, with M = 0.032 kg. v 0 2 ​ = 0.032 2 × 20.79 ​ = 1299 , so v 0 ​ = 36.0 m s − 1 .
