Section 5.1- Kinetic Theory of Matter

Question 1

all gases are completely ________________, and they diffuse very ________________

Answer 1

miscible (able to be mixed)
rapidly

Question 2

a gas is greatly affected by both __________ and _________________ changes

Answer 2

pressure
temperature

Question 3

the relationships of pressure and temperature to volume have been described in what are known as the

Answer 3

gas laws

Question 4

the observed behavior of gases as described in the gas laws can be explained in part by the

Answer 4

kinetic theory of matter (aka kinetic-molecular theory)

Question 5

the kinetic theory of matter has major assumptions as follows:

Answer 5

1. gas molecules are in constant, rapid motion, moving in straight lines until they collide with each other or with a solid or liquid
2. gas molecules undergo elastic collisions (no energy loss)
3. the kinetic energy of gas molecules is directly related to temperature
4. gas molecules are very far apart and are negligible in volume compared to the volume of the gas
5. gas molecules have negligible attraction between them

Question 6

the gas laws are relationships between ___________, which are measurable properties that may be varied

Answer 6

variables

Question 7

a relation in which the value of one variable depends directly upon the value of another variable

Answer 7

direct proportion (x=ky or x/y=k)
