Name the three states of matter.

Gas, Liquid, Solid

200

A type of mixture that appears to be made up of just one thing

Homogeneous

200

The substance doing the breaking down

Solvent

200

When a liquid changes state and becomes a gas

Evaporating

300

The particles vibrate in place

Solid

300

What happens to the particles of a substance when it changes from a solid to a liquid?

The particles gain energy, move faster, and begin to move past each other, breaking the fixed structure of a solid.

Which is usually more than in a solution?

Solute or Solvent?

Solvent

How would you separate a mixture of sand, salt, and water? 

  • Filtration can be used to separate the sand from the saltwater mixture. The sand will remain in the filter paper, while the saltwater passes through.
  • Evaporation can then be used to separate the salt from the water. By heating the saltwater, the water will evaporate, leaving the salt behind.
