is a way of explaining the arrangement and movement of particles in a substance.
What are attractive forces?
What is temperature?
What is the Celsius scale?
A measure of the amount of heat in a substance or object.
A scale for measuring temperature, which is based on the boiling point and freezing point of water.
What are molecules made of?
Molecules are made of atoms.
Give an example of a solid, liquid, and gas
solid - ice
liquid - water
gas - water vapour
True or False
The greater the attractive forces between particles the closer they will be together.
True
Describe boiling point, freezing point, and melting point.
Boiling point - The point at which liquid boils and turns to gas
Freezing point - The point at which liquid turns to a solid
The point at which a solid melts and turns to a liquid
What is the smallest part of matter?
An atom is the smallest part of matter.
solid, liquid, and gas.
What is the boiling point of water?
What is the freezing point of water?
0 degrees Celsius
100 degrees Celsius
What are the three states of matter?
Solid, Liquid, and Gas
Describe the arrangement and movement of particles in a solid, liquid, and gas
solid - all particles vibrate in place and will be very close together
liquid - particles slide past each other and are separated by spaces.
gas - particles will be constantly moving in all directions. Particles will be farthest from each other.
True or False
If a liquid thermometer breaks, you can quickly clean it up yourself.
False
If a liquid thermometer breaks, do NOT clean it up yourself. Tell an adult.
What is the difference between mass and volume?
Mass is the amount of matter in a solid, liquid, or gas.
Volume is the amount of space a solid, liquid, or gas takes up.
What is the particle model of matter?
The particle model of matter is a way of explaining the arrangement and movement of particles in a substance.
It states that all matter says that:
- all matter is made up of particles
- particles are always moving
- particles have spaces between them
