Gas Laws (Exam 2)

Question 1

Boyle’s Law

Answer 1

relates volume and pressure
the pressure of a gas increases as its volume decreases, assuming constant temperature and mass
P1V1=P2V2

Question 2

Charles’s Law

Answer 2

relates volume and temperature (in Kelvin)
the volume of a gas is directly proportional to the temperature at constant pressure
V1/T1=V2/T2

Question 3

Amonton’s Law

Answer 3

relates pressure and temperature
as temperature increases, pressure increases at constant mass and volume
P1/T1=P2/T2

Question 4

Avogadro’s Law

Answer 4

relates volume and moles
as moles increase, volume increases at constant temperature and pressure
volume(initial)*moles(final)=
volume(final) * moles(initial)

Question 5

Combined Gas Law

Answer 5

the ratio of pressure and volume to the absolute temperature of a gas is a constant
PV/T = constant for constant moles

Question 6

Ideal Gas Law

Answer 6

the equation of state of an ideal gas that relates pressure, volume, quantity of gas, and absolute temperature
PV=nRT
P= pressure
V= volume
n= number of moles of gas
T= absolute temperature

Question 7

Dalton’s Law of Partial Pressure

Answer 7

the sum of the pressure of each gas in a mixture is equal to the total pressure of the mixture
P total = P1+P2+P3+…
