Introduction to Matter

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that matter is neither created nor destroyed in a chemical reaction; it is only rearranged to form new substances.

How do you calculate density?

Back

Density is calculated using the formula: Density = Mass / Volume.

Front

What is the density of an object with a mass of 16 grams and a volume of 8 cubic centimeters?

Back

The density is 2.0 g/cm³.

Front

What is the volume of a graduated cylinder that reads 35 mL?

Back

The volume measurement is 35 mL.

Front

If a solid quartz with a density of 2.7 g/cm³ is placed in liquids of varying densities, which liquids will it pass through?

Back

The quartz will pass through liquids W, X, and Y, but not Z.

Front

What happens to the water level in a graduated cylinder when an object is submerged?

Back

The water level rises by the volume of the submerged object, demonstrating the principle of displacement.

Front

What is the definition of matter?

Back

Matter is anything that has mass and occupies space.

Front

What are the three states of matter?

How does temperature affect the state of matter?

Back

Increasing temperature can change a solid to a liquid (melting) or a liquid to a gas (evaporation), while decreasing temperature can change a gas to a liquid (condensation) or a liquid to a solid (freezing).
