G10 The Gas Laws

Question 1

states that the pressure (P) and volume (V) of a confined gas are inversely proportional to one another, given that the temperature of the system is held constant

Answer 1

Boyle’s Law

Question 2

It was first proven by Robert Boyle, a British chemist.

Answer 2

Boyle’s Law

Question 3

states that the pressure (P) and volume (V) of a confined gas are _ proportional to one another, given that the temperature of the system is held constant

Boyle’s Law

Answer 3

inversely

Question 4

constant of Boyle’s Law

Answer 4

temperature

Question 5

Boyle’s law can be mathematically expressed as

Answer 5

P=k/V

P1V1=P2V2

Question 6

The volume of the air inside the lungs is governed by the rib cage and the diaphragm.

The lung volume increases when the rib cage expands and the diaphragm moves downward, decreasing the air pressure inside the lungs

Answer 6

Application of Boyle’s Law

Breathing can be explained by Boyle’s law.

Question 7

It states that the temperature (T) and the volume V

of a confined gas are directly proportional given that the pressure of the system is held constant.

Answer 7

Charles’s Law

Question 8

It was first proven by Jacques Charles.

Answer 8

Charles’s Law

Question 9

It states that the temperature (T) and the volume V

of a confined gas are _ proportional given that the pressure of the system is held constant.

Answer 9

directly

Question 10

constant of Charles’s Law

Answer 10

pressure

Question 11

Charles’s law can be mathematically expressed as

Answer 11

V=kT

V1/T1=V2/T2

Question 12

In its deflated form, the balloon contains gas of the same kind as the surrounding air.
When the heat source inside the balloon (near the bottom) is ignited, the air will expand, and the balloon will inflate.
The air inside the balloon will then have a lower density than the surrounding air, enabling it to float.

Answer 12

Application of Charles’s Law

Charles’s law can be demonstrated using hot air balloons.

Question 13

states that the volume (V) and the amount (n) of a confined gas are directly proportional, given that the pressure and the temperature of the system are held constant

Answer 13

Avogadro’s Law

Question 14

It was first proven by Amedeo Avogadro after supporting the observations of Joseph Louis Gay Lussacs’s law of combining volumes.

Answer 14

Avogadro’s Law

Question 15

Avogadro’s law can be mathematically expressed as

Answer 15

V=kn

V1/n1=V2/n2

Question 16

Boyle's Law, 
 P∝1/V
 at constant T and n
Charles's Law, 
 V∝T
 at constant P and n
Avogadro's Law, 
 V∝n
 at constant T and  P

Question 17

Derivation of the Ideal Gas Law

Answer 17

V∝nT/P

V=knT/P

Question 18

Ideal Gas Law

Answer 18

V=RnT/P

PV=nRT
