KMT Flashcards
Provides an overview of the microscopic properties of molecules and their interactions.
Kinetic molecular theory
What does kinetic molecular theory states?
- Matter is composed of small particles
- Molecules interact through attractive forces
- Molecules are in constant random motion
- Temperature is the measure of average kinetic energy
The molecular motion depends on ___ and ___ ?
Temperature and intermolecular force
How does solid, liquid, and gas move?
Solid - Restricted motion, vibrates
Liquid - Move past each other, small distances, collide
Gas - Move freely, long distances
In KE,
As the heat increases, the kinetic energy (energy in motion) _____ ?
Increases
KMT Properties of Matter:
- At _____ temperature, intermolecular forces determine the state of a substance.
- The physical state of matter is affected by both ___ and ___.
- At ___ temperature, intermolecular forces dominate.
- At ___ temperature, the molecules have higher kinetic energy and will be able to overcome the intermolecular forces.
- Lower
- Kinetic energy and intermolecular forces
- Lower
- Higher
What are the two types of attractive forces?
Intramolecular (within) and intermolecular (between)
It holds the particle together in ionic, covalent, and metallic bonds.
Intramolecular forces
It is responsible for the properties of matter.
Intermolecular forces
Strength of intermolecular force in each state of matter.
Solid - Strong
Liquid - Intermediate
Gas - Weak
The higher the temperature, the ___ intermolecular force.
Weaker
The higher the kinetic energy, the ___ intermolecular force.
Weaker
