Gas flows adiabatically through a small opening from a closed vessel into a vacuum space. Constant gas pressure in the vessel is maintained by moving the piston. At the same time, the temperature of the gas in the vessel also does not change, and its temperature outside the vessel decreases to almost 0 K due to adiabatic expansion. Use the law of conservation of energy to estimate the velocity of a gas jet in a vacuum. Temperature of the gas in the vessel T, molar mass of the gas µ, molar heat capacity of the gas at constant pressure c_P
