A stationary cylinder of oxygent used in a hospital has the following characteristics at room temperature `300 K`, gauge pressure `1.38 xx 10^(7)` Pa. volume `16 L`. If the flow area, measured at atmospheric pressure, is constant at `2.4 L//min`, the cylinder will last for nearly

A cylinder of oxygen, used as medical aid, has a volume of 16 L. It is filled to a pressure of 1.37 x× 10^(7) Nm^(–2) above the atmospheric pressure at room temperature of 300 K. When in use, the flow rate at atmospheric pressure is 2.4 L//"min" . How long will the cylinder last? Atmospheric pressure is 10^(5) Nm^(– 2) .

A certain ideal gas has a temperature 300 K and a pressure 5.0 xx 10^4 Pa. The molecules have a mean free path of 4.0 xx 10^(-7) m. If the temperature is raised to 350 K and the pressure is reduced to 1.0 xx 10^4 Pa the mean free path is then

A sample of gas at 20^(@)C occupies a volume of 2 L at a pressure of 0.867xx10^(5)Pa . Calculate its volume at 100 kPa atmospheric pressure.

Air in the cyclinder of a diesel engine is compressed to 1/15 of its initial volume. If initial temperature is 300K and initial pressure is 10^(5)Pa , find the final temperature and final pressure. Take gamma= 1.4 .

A cylinder of cross-section area. A has two pistons of negligible mass separated by distances l loaded with spring of negligible mass. An ideal gas at temperature T_(1) is in the cylinder where the springs are relaxed. When the gas is heated by some means its temperature becomes T_(2) and the springs get compressed by (l)/(2) each . if P_(0) is atmospheric pressure and spring constant k= (2P_(0)A)/(l) , then find the ratio of T_(2) and T_(1) .
