Gases Flashcards
As the volume of a trapped gas increases, the pressure of the gas:
decreases
Gases have the___ entropy and ___amount of intermolecular space.
high entropy
high intermolecular space
With gases, as volume decreases, what happens to its temperature?
Increases
As the volume of a gas decreases
Its pressure increases
As a gas is heated:
Volume of the gas increases due to the increase in entropy of the gas
As the volume of a container holding a trapped gas is decreased, and no additional gas is allowed to enter the container
Pressure of the gas increases
A trapped gas has its volume kept constant as more gas is added to its container. What happens to the temperature of the gas?
It rises/gets hotter
Gas pressure is created just by collisions off the walls of the container.
?false
With Boyle’s Law, the two gas variables are pressure and temperature.
false
PV=PV
With Charles’ Law, the two gas variables are temperature and pressure.
false
V/T=V/T
Off the periodic table, the only non-diatomic gases are the Noble gases.
true
A gas can be poured as long as it is denser than the surrounding
atmosphere.
?true
An airtight cylinder has a moveable piston on one end of it. The piston pulls outward and increases the volume. What happens to the trapped gas?
As volume increases, the movement of the gas particles becomes less random as collisions decrease and pressure decreases
Air pressure decreases as altitude decreases.
FALSE
Why is pressure so slight very high in the sky?
less gravity = less atmospheric gases
