Which of the following describes objects that are formed of molecules very close together with little room to move or are made up of molecules with repeating crystalline patterns? choose the correct answer.
Colloid
Gas
Liquid
Solid
Solid
solid
The correct answer is "Solid".
Solids are described as objects that are formed of molecules very close together with little room to move or are made up of molecules with repeating crystalline patterns.
To arrive at this answer, we can use our knowledge of the different states of matter.
- A **Gas** is a state of matter where molecules are far apart and have a lot of freedom to move. The molecules are not closely packed together and do not have a repeating pattern.
- A **Liquid** is a state of matter where molecules are close together and have some ability to move. While the molecules are closer than in a gas, they still do not have a repeating pattern.
- A **Colloid** refers to a mixture in which tiny particles of one substance are dispersed evenly throughout another substance. Colloids can exist in any state of matter (solid, liquid, or gas) and do not necessarily have closely packed or repeating molecular patterns.
- A **Solid** is a state of matter where molecules are tightly packed and have little room to move. The molecules in a solid are held together in a repeating crystalline pattern.
Based on these descriptions, it becomes clear that "Solid" is the correct answer for objects formed of closely packed molecules with repeating crystalline patterns.
