Question 22

ideal gas

Answer 22

hypothetical gas,

• where molecules bounce off each other
• have negligible size
• do not come in contact with each other

Question 23

when is a gas closest to this “ideal gas” state

Answer 23

high temperature and low pressure

freer to move

Question 24

ideal gases obey how many gas laws

Answer 24

all of them

Question 25

most gases behave

Answer 25

approximately to ideal gases

Question 26

list some things all ideal gases do (4)

Answer 26

• move constantly, in a straight line
• small, mostly empty space
• no force of attraction between molecules
• no transfer of energy

Question 27

average kinetic energy depends on

Answer 27

temperature

Question 28

exceptions of ideal gases

Answer 28

• gases at a low temperature (more of a chance for interaction)
• very high pressure

Question 29

intermolecular

Answer 29

between molecules

Question 30

intramolecular

Answer 30

inside molecules

Question 31

what is the equation for ideal gas law

Answer 31

PV= nRT

Question 32
