Pre-test - Properties Of Matter U3

1. Matter is

Anything that has mass and color

Anything that reflects light

Anything that has mass and volume

Anything that is visible

Matter refers to anything that has mass and occupies space, which is described by its volume. This definition encompasses all physical substances, whether they are visible or not. The answer "Anything that has mass and volume" accurately captures the essence of matter, as it highlights the fundamental characteristics that distinguish it from non-material entities.

2. The ability to react with oxygen is a __________________ property.

Physical - intensive

Chemical - intensive

Chemical - extensive

Physical - extensive

React is a chemical word and intensive because the amount of matter you have doesn't change the ability for the oxygen to react.

Explanation

React is a chemical word and intensive because the amount of matter you have doesn't change the ability for the oxygen to react.

3. Which of the following matches the property with the proper tool and measurement unit:

Mass-graduated cylinder-mL

Volume-graduated cylinder-mL

Length-ruler-gram

Volume-graduated cylinder-gram

The answer is correct because volume is the property that is measured using a graduated cylinder, and the unit of measurement for volume is milliliters (mL). A graduated cylinder is a tool specifically designed to measure the volume of liquids accurately, making it the appropriate tool for measuring volume. The unit of measurement, mL, is commonly used to measure small volumes, such as those typically encountered in a laboratory setting.

4. Fruit can turn brown is a ________________ change.

Physical - intensive

Chemical - intensive

Chemical - extensive

Physical - extensive

Color change is a indecation of a chemical property and the amount of fruit you have doesn't change the fact that it can turn brown, intensive

Explanation

Color change is a indecation of a chemical property and the amount of fruit you have doesn't change the fact that it can turn brown, intensive

5. Ice melting is a ________________ change.

Physical - extensive

Chemical - extensive

Physical - intensive

Chemical - intensive

Melting is a physical word and the amount of matter you have doesn't affect the fact that it melts, which makes it intensive.

Explanation

Melting is a physical word and the amount of matter you have doesn't affect the fact that it melts, which makes it intensive.

6. When different liquids are mixed together they will

Mix randomly

Settle with the most dense on top

Settle with the most dense in the middle

Settle with the most dense on the bottom

When different liquids are mixed together, they will settle with the most dense liquid on the bottom. This is because density is a measure of how much mass is packed into a given volume. The denser liquid will have more mass and therefore will sink to the bottom, while the less dense liquid will float on top. This settling occurs due to the force of gravity, which pulls objects with greater mass towards the center of the Earth. As a result, the most dense liquid will be found at the bottom of the mixture.

7. State of matter is a ________________________ property.

Physical - extensive

Chemical - extensive

Physical - intensive

Chemical - intensive

States of matter are physical in nature and it is intensive because the amount of matter you have doesn't change the state.

Explanation

States of matter are physical in nature and it is intensive because the amount of matter you have doesn't change the state.

8. Flammability is a ___________________ property.

Physical - extensive

Chemical - intensive

Physical - intensive

Chemical - extensive

Flammable is a chemical word, think burning and intensive because the amount of matter you have doesn't change the flammability. A drop is flammable and a gallon of it is flammable.

Explanation

Flammable is a chemical word, think burning and intensive because the amount of matter you have doesn't change the flammability. A drop is flammable and a gallon of it is flammable.

9. Combustibility is a ____________________ property.

Physical - extensive

Chemical - intensive

Physical - intensive

Chemical - extensive

Combustibility is a chemical word and it is intensive because the amount of matter you have doesn't change the fact that the matter is combustible.

Explanation

Combustibility is a chemical word and it is intensive because the amount of matter you have doesn't change the fact that the matter is combustible.

10. Density is a ___________________property.

Physical - extensive

Chemical - extensive

Chemical - intensive

Physical - intensive

Density is a physical word and it is intensive because the amount of matter you have doesn't change the density of the matter.

Explanation

Density is a physical word and it is intensive because the amount of matter you have doesn't change the density of the matter.
