a battery; chemical reaction is used to produce electricity

Question 21

kinetic energy in gases

Answer 21

all gases have equal average kinetic energy at the same temperature.
small molecules move faster than bigger molecules

Question 22

kinetic theory of gases

Answer 22

a gas consist of tiny particles in random, elastic and chaotic motion that except during collisions they are widely separated from each other.

the volume of the particles is negligible compared to the volume of the container and the gas particles have no attraction for one another.

Question 23

pressure=

Answer 23

force/area

Question 24

diffusion

Answer 24

the ability of two or more gases to mix spontaneously until they form a uniform mixture

Question 25

effusion

Answer 25

a process by which gas molecules pass through a very small orifice from a container at higher pressure to one at lower pressure.

Question 26

rate of effusion

Answer 26

rate of effusion of A/rate of effusion of B= the inverse square root: b/a

Question 27

ideal gas law

Answer 27

PV=nRT

Question 28

standard temperature and pressure

Answer 28

R=0.0821 L atm/mol K OR 63.40 Ltorr/mol K T=273 K P= 1.00 atm V=22.4L

Question 29

relationship of pressure and volume

Answer 29

Pressure and Volume have an inverse relationship. When pressure goes up volume goes down, when pressure goes down, volume goes up.

Question 30

Answer 33

maximum amount that can be dissolved under certain conditions

Question 34

saturated

Answer 34

reached the limit of solubility(at or above solubility)

Question 35

unsaturated

Answer 35

below the solubility value

Question 36

relationship between pressure and solubility

Answer 36

high pressure increases the solubility of a gas in a liquid | low pressure decreases the solubility of a gas in a liquid

Question 37

effect of temperature on a solubility

Answer 37

a. agitation or stirring increases solubility b. particle size- the smaller the particles the faster the dissolution high temperature decreases the solubility of a gas in a liquid low temperature increases the solubility of a gas in a liquid
