Physical Science Review Midterm Review Part 2

Front

What is a solvent?

Back

A solvent is a substance that dissolves a solute, resulting in a solution. In the case of sugar dissolved in water, water is the solvent.

Front

What are physical properties?

Back

Physical properties are characteristics of a substance that can be observed or measured without changing its chemical identity, such as boiling point and freezing point.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. For example, a curling iron burning your hand is due to conduction.

What is a suspension?

Back

A suspension is a heterogeneous mixture in which solute-like particles settle out of a solvent-like phase. An example is orange juice with pulp.

Front

What is a physical change?

Back

A physical change is a change that affects one or more physical properties of a substance without altering its chemical composition. The substance remains the same after the change.

Front

What is a solute?

Back

A solute is a substance that is dissolved in a solvent to form a solution. In a sugar-water solution, sugar is the solute.

Front

What is a chemical property?

Back

A chemical property is a characteristic of a substance that can only be observed during a chemical reaction, such as reactivity with acid.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It occurs when warmer areas of a liquid or gas rise and cooler areas sink.
