Why is it harder to describe how fast a gas moves compared to how fast a car moves?
Gas particles are too small to see.
Gas particles move in many different directions at once.
Cars are much bigger than gas particles.
Gas particles do not have a fixed shape.
What does temperature actually measure in a system?
How hot or cold something feels.
The average kinetic energy of the particles.
The amount of heat in the system.
The speed of the fastest particles.
If two gas particles have the same kinetic energy, which one will move faster?
The heavier particle.
The lighter particle.
Both will move at the same speed.
It depends on the temperature.
What does Graham's Law of Effusion tell us about how gases move?
Lighter gases move slower than heavier gases.
Heavier gases move faster than lighter gases.
Lighter gases move faster than heavier gases.
All gases move at the same speed.
What is the process called when a substance spreads out from a high concentration area to a low concentration area until it is evenly distributed?
Effusion
Diffusion
Concentration gradient
Precipitation
When gases spread out through diffusion, how do their particles move?
They move together in a planned direction.
They move randomly and bump into each other.
They follow a specific path to find empty space.
They only move when pushed by other particles.
In the experiment where ammonia (NH3) and hydrochloric acid (HCl) gases were released into a tube, which gas traveled faster?
Hydrochloric acid (HCl) because it is heavier.
Ammonia (NH3) because it is lighter.
Both gases traveled at the same speed.
Neither gas moved because they reacted right away.
