Want this question answered?
Matter can exist in three states: solid, liquid?æ or gases. In solid, particles are two close to each other. In liquid,they are a bit a part while in?æ gases they are very far apart .
Gas
Because the particles are further apart (look up the particle model) :)
Yes. All atomic sized particles move, by vibrating. no matter how cold they are.
No, heating a liquid makes it's particles move farther apart (makes the liquid expand). This is most readily observed in an old glass thermometer. As your temperature goes up (as you heat the liquid in the thermometer), the liquid inside expands and travels up the thermometer.

If the object is heated it will expand because the particles gain energy from the heat and move about more vigorously causing them to bump into each other and move further and further apart. When the substance is cooled (gets cold) the particles slow down and move closer and closer together causing the object to contract.
I would describe it as this: All of the particles are tightly packed together with almost no spaces between them. Their motion is very limited, unlike that of a gas where the particles are spaced further apart and they are free to move around more.
Gas
Closer
the particles get closer together because my class just talked about that stuff!!
No, farther apart.
The molecules in a gas are spread further apart than those in a liquid.
particles are further apart and allows water to flow
Yes they are. They become even further apart when they get more energy (warm up).
Compression is the areas where the particles are closer together. Rarefaction is the areas where the particles are stretched apart.
