Gases and Kinetic Theory

Question 1

The state of a gas can be defined by _______, ________, _________, and _______

Answer 1

pressure, volume, temperature, and amount of gas in moles

Question 2

Standard Temperature and Pressure (STP) =

Answer 2

273 K (0 C) and 1 atm

Question 3

Ideal gas law equation

Answer 3

P1V1/T1 = P2V2/T2

Question 4

If a temperature remains constant during a process (_______), then the equation becomes:

Answer 4

isothermic, P1V1 = P2V2 (Boyle’s Law)

Question 5

If the volume remains constant during a process (_______), the equation becomes:

Answer 5

isochoric, P1/T1 = P2/T2

Question 6

If the pressure remains constant during the process (_________), the equation becomes:

Answer 6

isobaric, V1/T1 = V2/T2 (Charles’s Law)

Question 7

When setting up an equation, ALWAYS convert ______ to ______

Answer 7

Celsius to Kelvin (C -> K)

Question 8

5 Assumptions of the kinetic theory of gases:

Answer 8

1. Gases are made up of particles whose volumes are negligible compared to the container volume 2. gas atoms or molecules exhibit no intermolecular attractions or repulsions 3. Gas particles are in continuous, random motion, undergoing collisions with other particles and the container walls 4. Collisions between any two gas particles are elastic, meaning that no energy is dissipated and kinetic energy is conserved 5. The average kinetic energy of gas particles is proportional to the absolute (Kelvin) temperature of the gas, and is the same for all gases at a given temperature
