Gas Pressure
WHAT IS PRESSURE Pressure is a force exerted by the substance per unit area on another substance. The pressure of a gas is the force that the gas exerts on the walls of its container. When you blow air into a balloon, the balloon expands because the pressure of air molecules is greater on the insid... Read more

Laws of Gases
THE GAS LAWSTHE GAS LAWS were developed at the end of the 18th century, when scientists began to realize that relationships between pressure, volume and temperature of a sample of gas could be obtained which would hold to approximation for all gases. Gases behave in a similar way over a wide variety... Read more

Total and Average Kinetic Energy
[1] A tank used for filling helium balloons has a volume of 0.300 m3 and contains 2.00 mol of helium gas at 20.0°C. Assume that the helium behaves like an ideal gas. (A) What is the total translational kinetic energy of the gas molecules? (B) What is the average kinetic energy per molecule? [2... Read more

nonideal behavior of Gases
If 1.000 mol of an ideal gas were confined to 22.41 L at 0.0°C, it would exert a pressure of 1.000 atm. Use the van der Waals equation to estimate the pressure exerted by 1.000 mol of Cl2(_g_) in 22.41 L at 0.0°C (a = 6.49 L2-atm/mol2, b = 0.0562 , R = 0.08206 L-atm/mol-K).... Read more

APPLICATIONS OF THE GAS LAWS REACTION IN CAR ENGINE In a car engine, a reaction occurs in which fewer moles of gasoline and O2 form more moles of CO2 and H2O vapor, and Read more

Effusion and Diffusion of Gases

2018-11-14 22:58:06 Kinetic Theory 321 C
EFFUSION: the process by which a gas escapes through a tiny hole in its container into an evacuated space. THOMAS GRAHAM studied the _EFFUSION__RATE_ of a gas, “the nu Read more

The Critical Point
