Answer 11

An example of breathing, specifically spontaneous breathing without positive pressure.

Question 12

What is a practical example of Charles’ Law?

Answer 12

Cuff on ETT or LMA increases at temperature increases

Question 13

Which law says that as temperature increases, volume will increase?

Answer 13

Charles’ law

Question 14

Who first conceived that hydrogen is lighter than air?

Charles

Question 15

How do you calculate Kelvin?

Answer 15

Celsius + 273

Question 16

At absolute zero, what happens to volume?

Answer 16

It is also zero.

Question 17

Gay Lussac’s Law relates what two values?

Answer 17

Pressure and temperature are directly proportional.

Question 18

What is a practical example of Gay-Lussac’s law?

Answer 18

N2O cylinder. As gas is released, the liquid in tank vaporizes and heat is lost. Temp in cylinder falls and the pressure drops.

Question 20

What does Avogadro’s Law state?

Answer 20

The volume of gas is directly proportional to the number of gas molecules as long as the temperature and pressure are constant.

Answer 22

Temperature and pressure

Question 23

Dalton’s Law of Partial pressures states?

Answer 23

That the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases.

Question 24

Explain Mole fraction:

Answer 24

Mole fraction is dividing the number of moles in a particular gas by the combined number of moles in the mixture of gases.
