The Ideal Gas Law Applications Practice Problems

How does the application of force to the person's waist during the Heimlich maneuver create enough pressure to expel an obstruction from the trachea?

An expandable container is filled with hydrogen gas and oxygen gas. Hydrogen gas has a partial pressure of 0.75 atm and oxygen gas has a partial pressure of 1.45 atm. Which of the diagrams (A–C) represents the change in volume of the container when the Kelvin temperature is decreased by half and the number of gas molecules is doubled at constant pressure?

Select the diagram that depicts the change in volume of a gas sample in a container when the pressure and the Kelvin temperature of the system are both tripled.

Which of the following diagrams represents the change in volume of a gas sample when the total pressure in the system increases without any temperature change?

The following diagrams are at a constant temperature of 40°C. Select the diagram that depicts a gas sample exerting the lowest pressure.

Consider two tanks with identical volumes, and both are at the same temperature. The first tank contains 3.5 g of F₂ gas, while the second tank contains 3.5 g of Cl₂ gas. Determine whether the following statement is true or false. Justify your answer. 

The pressure in the first tank is greater than the pressure in the second tank.

The ideal gas equation is PV = nRT. In the equation, P and V are

Identify which parameters remain constant in the following example: 

A sample of gas in a fixed-volume container is heated. Assume that there are no physical or chemical changes that occur.
