Anything that occupies space and has mass.

Properties that can be observed or measured by changing the chemical nature of the substance.

The molecules are close together but not held in fixed positions. They are arranged in a disorderly manner and can move freely.

This separation technique is similar to sublimation. The impure solid is dissolved in a solvent. The solution is heated and evaporation takes place. The hot solution is allowed to cool and crystals will gradually form.

This separation technique is applicable for separating a liquid mixture. As you heat the liquid, it evaporates and the solid crystals will start to form as sublimate.

Consists of only one kind of atom.

Properties that can be observed or measured without changing the composition of the substance.

This technique separates an undissolved solid from a liquid using filter paper.

Mixtures can be broken down into _____ and _____.

This separation technique purifies a liquid mixture by using the boiling points of its substances.

Pure substances can be broken down into _____ and _____.

This separation technique separates an undissolved solid from a liquid.
