5.PS.1 Matter and its Interactions

Front

What is matter?

Back

Matter is anything that has mass and takes up space.

Front

What is solubility?

Back

Solubility is the ability of a substance to dissolve in a solvent, such as water.

Front

What happens to sugar when it is heated in water?

Back

Heating water increases the solubility of sugar, allowing it to dissolve more easily.

Front

What is the relationship between temperature and solubility?

Back

Generally, as temperature increases, the solubility of solids in liquids also increases.

Front

What is a mixture?

Back

A mixture is a combination of two or more substances that are not chemically bonded.

Front

What happens to the mass of a closed system during a chemical reaction?

Back

The total mass remains constant; it does not change because matter is neither created nor destroyed.

Front

What is the effect of stirring on the rate of dissolving?

Back

Stirring increases the rate of dissolving by distributing the solute particles throughout the solvent.

Front

What is a saturated solution?

Back

A saturated solution is one in which no more solute can dissolve at a given temperature.

Front

What is the difference between a solid and a liquid?

Back

Solids have a definite shape and volume, while liquids have a definite volume but take the shape of their container.

Front

What is evaporation?

Back

Evaporation is the process by which liquid turns into vapor, usually due to heat.
