Question

1. which states of matter both have a fixed volume?

a. gas and liquid
b. solid and liquid
c. gas and solid
d. plasma and gas

1. state of matter is a physical property of matter.

a. true
b. false

1. which type of matter is commonly found in the universe, but not commonly found on earth?

a. plasma
b. liquid
c. gas
d. solid

1. suppose you have three identical test tubes that contain equal masses of a solid, liquid, an same substance. which form of the substance has the largest volume and why?

a. gas: it expands to fill the container.
b. none: all of them have the same volume.
c. solid: it has the hardest surface.
d. liquid: it takes the shape of the container.

1. liquids take the shape of their containers, because the particles:

a. can flow past each other
b. can vibrate very quickly
c. can oscillate very fast
d. none of the above

Explanation:

1. Solids have a fixed shape and volume. Liquids have a fixed volume but take the shape of their container. Gases have neither a fixed shape nor volume. Plasma (a state of matter) also has no fixed volume or shape. So, solid and liquid have a fixed volume.
2. State of matter (e.g., solid, liquid, gas) is a physical property as it can be observed without changing the substance's chemical composition.
3. Plasma is commonly found in stars (like the Sun) in the universe. On Earth, it's less common (e.g., in neon signs but not as prevalent as solids, liquids, and gases in daily - life natural settings).
4. Gases expand to fill their container. Since the test tubes are identical (same - sized containers), the gas form of the substance will have the largest volume among the three (solid, liquid, gas) for the same mass.
5. In liquids, particles can flow past each other, which allows the liquid to take the shape of its container. In solids, particles vibrate around fixed positions, and in gases, particles move freely in all directions.

Answer:

1. b. solid and liquid
2. a. True
3. a. plasma
4. a. Gas: It expands to fill the container.
5. a. Can flow past each other
