Question 6
1 Point
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
1 Point
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).

Question 8
1 Point
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. A scuba diver has been brought into the hospital because he had to come up really
quickly since his oxygen tank was running out. The problem with doing this is that it causes a
phenomenon called “bends” where the volume of the oxygen in the blood stream can increase too
quickly if the pressure around the body is changed too quickly. If the scuba diver had 4.0 L of gas at
atmospheric pressure, what was the volume of the gas when scuba diver dove down to 130ft below sea
level (110kPa)?

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),

1 Point
You are a nurse and you have several patients that need treatment. Thank goodness you were taught
