Kinnetic Molecular Theory Flashcards
Kinetic molecular theory explains how
Gases behave
Kinetic molecular theory is theory that gases consist of
Molecules in constant random motion
Principles that comprise kinetic molecular theory
Ideal gases
- Gases are made of particles that
Remain in a state of constant random motion
- Gas particles don’t have any (2)
Attraction
Repulsion
(Intermolecular forces)
- And will move continuously in straight line until
Collide with another particle or side of container
- Gas particles are extremely
Small
- Smaller than the space between them which is why
Gas mostly empty space
- Average _ of gas depends on temp of gas and nothing else
Kinetic energy
- Collisions between particles are
Elastic
- Elastic collision means they do not _ from one particle to another
Transfer energy
- Elastic collision means energy not transferred from one particle to another and
No energy lost
Kinetic energy is energy of
Movement
_ is the stored energy an object has because of its position relative to other objects
Potential energy
If you are sitting in a chair, you have potential energy because
Chair holding you off the floor
While sitting in a chair, energy is stored because of
Your position (potential energy)
Gas molecules are in constant motion, therefore they have
High kinetic energy
_ directly affects kinetic energy
Temp
As temp increases, gas particles
Move more quickly
The more kinetic energy a gas has, the more
Collisions its particles will have
Greater the number of gas molecules
Greater number of collisions
