Gases Flashcards
How are placed the gases molecules?
They’re alway moving around thanks to kinetic energy.
What happens when a gas is compressed?
It can transform into a liquid or a solid.
Are pressure and temperature important for gases?
YES, as they’re the one’s who’ll be in charge of transforming the gas.
How can you have pure gases?
With 1 atom or a single compound.
How can some gases transform into a solid?
Thorugh void sealing.
Do gases have high density?
FALSE
They have low density.
What is diffusion?
It’s when a gas moves from one container to another.
What is effusion?
It’s when a gas escapes from a small hole in a container.
Ex. when a ball is pinched the air inside it would get out from that tiny hole.
How can pressure be measured?
By pascals, psi, milimiter of mercury, torr, or atmosphere.
What is Charles Law?
The volume of a gas equals to a constant value multiplied by its temperature, measured on Kelvins.
Simple:
When the pressure is being held constant, but the volume depends on the temperature.
What is Charles Law formula?
V1/T1 = V2/T2
Volume= V
Temperature=T
What is Boyle’s Law?
TEMPERATURE is held constant, but as volume increases, pressure decreases.
What is Boyle’s formula?
V1/P1 = V2/P2 Volume= V Pressure= P
What is Gay-Lussac’s Law?
When VOLUME is constant, but pressure increases and temperature decreases.
What is Gay-Lussac’s formula?
P1/T1 = P2/T2 Pressure= P Temperature= T
