P. 4395. In a container there is a sample of Hydrogen gas, its gauge pressure is 400 Pa. If a small valve (its diameter is some millimetres) at the top of the container is opened, then the initial speed of the leaking Hydrogen is 100 m/s. What was the temperature of the Hydrogen? (The ambient air pressure is 1 bar.)
