The energy of motion
Kinetic energy
Compression, contraction, or expansion.
Lots of gas particles are forced into a ball.
Compresssion
Increase or decrease in kinetic energy if:
Contraction of particles happens
Decrease kinetic energy
What happens to particles when?
A water bottle is put in the freezer
Solid, liquid or gas
Particles are far apart
Gas
energy transfer that increases the kinetic energy of a substance’s particles
Heating
Compression, contraction, or expansion.
A ball was popped, and the air rushes out
Expansion
Increase or decrease in kinetic energy if:
Heat was added
Increase kinetic energy
What happens to particles when?
Metal is melted
Expansion
Solid, liquid or gas.
Particles are close together but still slide past each other.
Liquid
the smallest piece of a substance that is still that substance
Particle
Compression, contraction, or expansion.
A metal ring is placed in cold water. Now a sphere won't fit through it.
contraction
Increase or decrease in kinetic energy if:
Expansion of particles happens
Increase in kinetic energy
What happens to particles when?
Air is pressed inside a syringe
Compression
Solid, liquid or gas.
Particles are close together but do not move past each other.
Soild
the average kinetic energy of the particles in the air and other objects in a typical comfortable room
Room temperature
Compression, contraction, or expansion.
A ring was stuck on my finger, so I put it under hot water. Now the ring comes off.
Expansion.
Increase or decrease in kinetic energy if:
You add ice to juice.
Decrease in kinetic energy
What happens to particles when?
Someone turns on the heat.
Expansion
Draw what liquid looks like at the particle level with high kinetic energy
Teacher use brain
a phase of matter that has definite volume but no definite shape. Loosely bonded particles in liquid can flow over and around one another.
liquid
Compression, contraction, or expansion.
A thermometer is placed in cold water and the liquid inside goes down.
Contraction
Increase or decrease in kinetic energy if:
Hot water cools to room temperature
Decrease in kinetic energy
What happens to particles when?
Metal is put in the freezer.
Contraction
Draw a diagram of a Gas particle with low kinetic energy
Teacher use brain
