Separating Mixtures

What is sorting?

• Sorting is the process of organizing items based on their size or color.

• Sorting is the process of separating items based on specific characteristics or properties.

• Sorting is the method of combining different items into one group.

• Sorting is the technique of measuring the weight of items.

What tool is best for separating a mixture of rocks and sand?

• A strainer

• A magnet

• A sieve

• A filter

What is the role of heat in evaporation?

• Heat causes the liquid to freeze.

• Heat provides energy that allows liquid molecules to escape into the air as vapor.

• Heat has no effect on evaporation.

• Heat increases the density of the liquid.

What is a magnet used for in separation?

• To separate magnetic materials from non-magnetic materials.

• To generate electricity in circuits.

What is filtration?

• A method to combine liquids and gases

• A method used to separate solids from liquids or gases using a filter.

• A technique for heating substances to change their state

• A process of mixing different types of solids together.

How can salt be separated from water?

• By filtration

• By evaporation

What is a mixture?

• A combination of two or more substances that are not chemically bonded together.

• A single substance that cannot be separated into its components.
