Question

which among the following statements is false?
a liquid has a definite volume; but it has no definite shape.
a gas has neither definite volume nor definite shape.
a solid has a definite shape and a definite volume.
both solids and liquids are incompressible while gases are compressible.
none of the above

Explanation:

• Liquid: Molecules are close but can move. So, it has definite volume (molecules' amount fixed) but no definite shape (takes container's shape).
• Gas: Molecules are far apart and move freely. Thus, no definite volume (fills container) or shape.
• Solid: Molecules are fixed. Hence, definite shape and volume.
• Compressibility: Solids and liquids have little space between molecules (incompressible). Gases have large spaces (compressible).

Answer:

none of the above
