Which state of matter have no define shape or volume

Answer: Gas

Explanation: The molecules in gas are far apart and can move freely and rapidly. As a result, gasses can expand to fill a container and have a low density. Density just means how tightly packed particles are and since gas has a low density, the particles are very loosely packed. Gasses do not have a fixed shape or volume so they can be compressed, reducing the space between their particles.
