Question

Long Answer Type:
Write the difference between a solid, a liquid and a gas in terms of molecular arrangement.
​

Answer 1

Particles in a:

gas are well separated with no regular arrangement.

liquid are close together with no regular arrangement.

solid are tightly packed, usually in a regular pattern.

Particles in a:

gas vibrate and move freely at high speeds.

liquid vibrate, move about, and slide past each other.

solid vibrate (jiggle) but generally do not move from place to place.

Answer 2

Explanation:

solid :

• It is a form of matter having a rigid structure and firm shape
• It has the lowest energy
• These are hard to compress
• It has a fixed shape plus volume
• Molecules are regular and arranged closely

Liquid :

• They are substances flowing freely with no permanent shape but a definite volume
• It has medium energy
• You can compress them a little difficulty
• No fixed shape but they do have volume
• Randomly molecules arranged sparsely

gas :

• Gas is a state of matter which does not have a shape but takes the shape of the container you put in it
• They have the highest energyThese are easily compressible
• They have neither definite shape nor volume
• These are easily compressible
• Their molecules are random and arranged more sparsely
