Chapter 8- Gas Phase

Question 1

Units for gas pressures

Answer 1

1atm = 760 mmHg = 760 torr = 101.325 kPa

Question 2

STP

Answer 2

Used when calculating ideal gases

T: 273 Kelvin
P: 1 atm

Question 3

Ideal gas

Answer 3

Hypothetical gas with molecules with no intermolecular forces.

Occupy no volume.

Compressed real gases behave like ideal gases.

Question 4

Ideal gas law

Answer 4

PV=nRT

P-pressure 
V-volume 
n-number of moles 
R-ideal gas constant 8.21x10^-2
T-temperature
