Gases

Question 1

1 atm

Answer 1

760 mm Hg

Question 2

760 mm Hg

Answer 2

760 torr

Question 3

760 torr

Answer 3

101325 Pa

Question 4

a gas is composed of small particles travelling in a constant, random, straight-line motion

a gas is mostly empty space; particles are far from each other

particles elastically collide with one another and the sides of the container

there are no intermolecular forces of attraction

the kinetic energy of the gas is dependent only on its temperature

Answer 4

kinetic molecular theory

Question 5

properties of gases

Answer 5

low density - indefinite shape or volume - compressibility or expandability - diffusivity

Question 6

gases contain scattered molecules that are dispersed across a given volume and are therefore less _____ than in their solid or liquid states

Answer 6

low density

Question 7

the random movement of gas molecules allows them to expand or contract to assume the volume of the container holding them

gas’ volume refers to the spaces of the container in which its molecules have the range to move

Answer 7

indefinite shape or volume

Question 8

low density makes them compressible since their molecules can be positioned far apart from one another

Answer 8

compressibility or expandability

Question 9

two or more gases can mix quickly and easily with one another to form a homogenous mixture

Answer 9

diffusion
