If it has enough kinetic energy

A vertical cylinder of cross-sectional area 0.1m^2 closed at both ends is fitted with a frictionless piston of mass M dividing the cylinder into two parts. Each part contains one mole of an ideal gas in equilibrium at 300K. The volume of the upper part is 0.1m^3 and that of lower part is 0.05m^3 .What [...]

A tall vertical cylinder of height and cross-sectional area A is in uniform gravitational field. The cylinder contains an ideal gas at uniform temperature and is closed at both ends. If density of gas at bottom and and top of the a molecule at the surface of the earth can escape the Eartsh's gravitation which [...]

An ideal gas of molar mass M is filled in a horizontal cylinder closed at one end. The cylinder rotates with a constant angular velocity w about a vertical axis passing through the open end of the cylinder. The pressure at the axis of the cylinder is a molecule at the surface of the earth [...]

If it has enough kinetic energy, a molecule at the surface of the earth can escape the Earth’s gravitation which means that it can continue to move away from the Earth forever. Using the principle of conservation of energy, show that the minimum kinetic energy needed to-duplicate-1 a molecule at the surface of the earth [...]
