Express your answer in decimal form and calculate your answer to at least four sig figs. 4.690 Graham's Law of Effusion is: rate/ratez - (M/M)2 where M - molar mass A cylinder with a moveable piston contains 92g of Nitrogen. The external pressure is constant at 1.00 atm. The initial temperature is 200K. When the temperature is decreased by 70 K, by putting...
An 80.0-L volume of an ideal gas in a cylinder with a piston is at a pressure of 3.0atm. While the system is held at constant temperature, enough weight is placed on the piston to increase the external pressure to 10.0atm. For the resulting process, determine q(heat) and w(work) in units of kJ, and with proper signs. (Note: 1 L atm = 101.3 J)

An ideal gas is kept in a 88-liter [L] container at a pressure of 2.52.5 atmospheres [atm] and a temperature of 290290 kelvin [K]. If the gas is compressed until its pressure is raised to 55 atmospheres [atm] while holding the temperature constant, what is the new volume in units of liters [L]?
A cylinder contains 0.300 mol of carbon dioxide (CO2)gas at a temperature of 23.0 ∘C. The cylinder is provided with a frictionless piston, which maintains a constant pressure of 1.00 atm on the gas. The cylinder is placed on a hot plate and a 920 J of heat flows into the gas, thereby raising its temperature to 130 ∘C. Assume that the CO2 may be treated as an ideal gas. 1. What is the change in internal energy of the...
