Module 05 Quiz

Question 1

Describe the 4 standards that gases need to have in order to fit the kinetic molecular theory of gases.

Question 2

Describe how surface area, temperature, and intermolecular forces are related to the rate of evaporation of a liquid and vapor pressure.

Question 3

What are the 3 interactions that happens in a solution between the solute and the solvents? Describe the interactions in terms of salt dissolved in water.

Question 4

Why can’t the kinetic molecular theory be applied to liquids and solids?

Question 5

Identify which of these gases exhibit non-ideal gas behavior:

Gas A, Gas B, Gas C, Gas D, Gas E, Gas F

Question 6

A box contains 100 particles of gas at room temperature. What is the correlation between the volume and pressure in a box containing a certain amount of gas particles and why?

Question 7

You are a nurse and you have several patients that need treatment. Thank goodness you were taught how to manipulate gas laws in order to help the patients. Help each patient solve the issue they are encountering. Patient A has a collapsed lung and needs to be airlifted to a different hospital for treatment. You know from your schoolwork that pressure has an effect on volume, and the pressure changes as altitude changes. If the volume of the collapsed lung is at 1435mL on the ground (1 atm), what would the volume of the lung be at 632mmHg?

Question 8

You are a nurse and you have several patients that need treatment. Thank goodness you were taught how to manipulate gas laws in order to help the patients. Help each patient solve the issue they are encountering. You are checking the purity of the air in a unit of the hospital and find the following readings: CO2 (17.8 Pa), O2 (20.2 bar), CO (56.6 psi), N2 (71.7 mmHg), SO2 (22.4 torr), and Ar (42.3 atm). What is the total pressure of the unit?

Question 9

You are a nurse and you have several patients that need treatment. Thank goodness you were taught how to manipulate gas laws in order to help the patients. Help each patient solve the issue they are encountering. It is the middle of the summer and a room in the ICU is a lot warmer than it should be. A patient has been wheeled into the room and needs to be put on oxygen. When the room was at room temperature, the pressure in the gas was at 250 psi for 13L of gas. What is the pressure in the gas cylinder since the room warmed up and if the volume of the gas increased to 20L?

Question 10

You are a nurse and you have several patients that need treatment. Thank goodness you were taught how to manipulate gas laws in order to help the patients. Help each patient solve the issue they are encountering. Patient B needs nitrous oxide (N2O) before surgery, and you have to figure out if there is enough nitrous oxide in the cylinder. How many moles of nitrous oxide is in a cylinder of 9.0kg (6kg when empty) at standard temperature and pressure?

Question 29

Osmotic drug delivery is a technique used in the pharmaceutical industry to help an active drug dissolve when swallowed. There are holes that are drilled onto the outside of the tablet allowing for the phenomenon to occur. With your knowledge of how osmotic pressure works, hypothesize what you think happens when a drug is ingested into the body.

Question 30
