Answer: The atoms in a gas move at high speed.
The atoms in a gas spread in all directions.
A gas is a state of matter in, which atoms remains in a constant motion, they do not stick together. They are free and can move in all directions. The gas molecules expands to fill the available space. Hence, they can change shape and volume. The gas atoms being in a molecular state moves fast in high speed to break away from each other, to remain in a free state.
