Question 13

Amonton/Gay-Lussac’s Law

Answer 13

the pressure of a gas is directly proportional to its absolute temperature when the volume is held constant

Question 14

Boyle’s Law

Answer 14

the volume of a given amount of gas held at constant temperature is inversely proportional to the pressure under which it’s measured

Question 15

Avogadro’s Law

Answer 15

for a confined gas, volume and number of moles of a gas are directly proportional if maintained at constant temperature and constant pressure

Question 16

ideal gas law

Answer 16

PV=nRT

Question 17

KMT assumptions

Answer 17

-gas molecules are in continuous random motion, traveling in straight lines until a collision happens
-gas molecules/atoms have negligible volume compared to the volume they occupy
-collisions between molecules/atoms & the vessel wall exert pressure
-gas molecules/atoms exert no attractive forces on each other or on the vessel wall
-collisions are elastic
-average kinetic energy of a gas is proportional to the absolute temperature of a gas

Question 18

Van der Waals

Answer 18

pressure is underestimated & volume is overestimated

Question 19

Charle’s Law

Answer 19

the volume of a given amount of gas is directly proportional to its absolute temperature when the pressure is held constant
