Molecular Motion WITHOUT 3 Gas Laws
Transcript of Molecular Motion WITHOUT 3 Gas Laws
You are required to write everything that is not in BLACK starting with the definitions below. Anything written in BLACK is optional.
Kinetic Energy - The energy of motion.
A ball falling through the air has kinetic energy because it is moving. A rock on the ground doesn't have kinetic energy because it is not moving.
Temperature - The amount of kinetic energy that the particles of an object has.
Boiling water has a higher temperature than ice because the water molecules in boiling water are moving much faster than the water molecules in ice.
A solid has a definite shape because its particles don't have enough kinetic energy to overcome the force of attraction between them.
The particles of a solid are packed close together and are always vibrating.
Since solid particles stay in one spot and retain their shape, solids have a definite volume.
This is an example of how solid particles move
Liquid particles have enough kinetic energy to partially overcome the force of attraction between themselves. They can slide past each other, but have a hard time pulling apart completely.
Liquid particles stick together, so they have a definite volume.
Liquid particles slide past each other and take the shape of their container, so they don't have a definite shape.
This is an example of how liquid particles move
Gas particles have enough kinetic energy to escape the forces of attraction between them.
Gas particles spread out freely where ever they are.
Gases don’t have a definite shape and don't have a definite volume.
This is an example of how gas
Plasma doesn’t have a definite shape and only forms at high temperatures.
The particles in plasma have so much kinetic energy that the electrons break free from the atoms and you're left with atomic nuclei and electrons that move wherever they want.
Neon signs, lightening, and the sun are examples of plasma.
