Match the state of matter to its description.

Column A
1.
particles are tightly packed and vibrate in place; definite shape and volume:
particles are tightly packed and vibrate in place; definite shape and volume
2.
particles are loosely packed and slide past one another; indefinite shape but definite volume:
particles are loosely packed and slide past one another; indefinite shape but definite volume
3.
particles are far apart and move at fast speeds; indefinite shape and volume:
particles are far apart and move at fast speeds; indefinite shape and volume
Column B
a.solid
b.liquid
c.gas

1. a. solid

2. b. liquid
3. c. gas

To match the state of matter to its description, let's analyze each option in column A and then match it with the appropriate letter in column B.

1. Particles are tightly packed and vibrate in place; definite shape and volume:
This description corresponds to the state of matter called "solid," which is represented by letter (a) in column B.

2. Particles are loosely packed and slide past one another; indefinite shape but definite volume:
This description matches the state of matter known as "liquid," represented by letter (b) in column B.

3. Particles are far apart and move at fast speeds; indefinite shape and volume:
This description aligns with the state of matter called "gas," which is represented by letter (c) in column B.

Thus, the matching pairs are:
1. a. solid
2. b. liquid
3. c. gas

Matching the state of matter to its description:

Column A
1. particles are tightly packed and vibrate in place; definite shape and volume: a. solid
2. particles are loosely packed and slide past one another; indefinite shape but definite volume: b. liquid
3. particles are far apart and move at fast speeds; indefinite shape and volume: c. gas
