No, they are in motion in a liquid as well. In a solid they vibrate in place.

Are the molecules in a gas in constant motion?
Yes, the molecules of a gas are constantly in a random motion if the gas temperature is more than 0 degree kelvin. This random motion determines the average kinetic energy of the molecules which is equal to the temperature of the gas. I hope this answers your question.
What is the most appropriate to express number of molecules per volume?
Avogadro's number is the number of molecules in a mole of a substance. This is expressed as 6.022 141 29 E23 /mol. This is defined as the number of atoms in 12 grams of carbon12. A mole of any gas has this number of molecules. Any fraction of that mole must be divided into the number.
Four states of matter?
the four states of matter are a solid, liquid ,gas, and plasma the molecules in a solid are tightly packed together in a liquid they take the shape of its container a gas the molecules move freely and in plasma the molecules attract each other positive and negative
Gas particles travel at speeds of up to 500 meters per second then why does it take so long for gas molecules to travel the length of a room?
Because gas molecules continually collide with others. The result is a random path (known mathematically as a drunkard's walk) which results in a very long time to cover a significant distance.
When can volume fraction be equal to mole fraction?
The volume fraction of a substance is equal to the mole fraction for ideal gas mixture
What do you know about gases molecules?
Molecules of a gas are in permanent motion.
When are molecules of a substance in motion?
Molecules of a substance are in constant motion. Whether you have a solid, liquid, or gas, the particles are moving (but the speed and amount they move differs). Particles of a solid move the least (they basically vibrate), particles of a liquid can flow around one another, and particles of a gas have a lot of space between them because they move in random, constant motions.

Does gas molecules are constantly in motion?
Yes they do!
What are molecules in a gas?
In random motion.
What is the ability of the gas to completely spread out and mix with other substance?
This is entropy, the tendency for an ordered system to move to a state of lower energy (every thing evenly spread out). Brownian motion (haphazard random motion of molecules) accounts for the motion.
Compare the motion and spacing ofbthe molecules in a solid to the motion and spacing of molecules in a gas?
The motion of molecules in a solid will be extremely slow. The spacing is very close to one another.THe opposite is true of gas. The molecules are extremely fast and they are spaced far apart.
How does the motion of the gas molecules change?
Gas molecules change their motion when they bounce into the surfaces of their containers. If the surfaces absorb the impact, then energy is transfered out of the system and particle speed decreases.
What is the behaviour of gas molecules based on the kinetic theory?
Gas molecules are in continuous random motion and they collide with each other.
In which phases will the molecules of a substance fill whatever size container they are placed in?
This is a gas.
Molecule of a substance are in a motion?

Particles of a solid move the least (they basically vibrate), particles of a liquid can flow around one another, and particles of a gas have a lot of space between them because they move in random, constant motions.
