Question

which picture shows the state of matter with the following characteristics?

• has a definite, fixed volume.
• has a variable shape.
• particles are constantly moving and sliding by one another.

Explanation:

Step1: Recall states of matter properties

Liquids have definite volume, variable shape, and particles slide past each other. Solids (like dumbbells, D) have definite shape/volume; gases (like particles in A or C) have variable shape/volume, particles move freely.

Step2: Analyze each option

• Option A: Likely gas (particles spread, variable volume) – no.
• Option B: Appears to be a liquid (e.g., water-like, definite volume, variable shape, particles slide) – matches.
• Option C: Likely gas/ionized gas (particles spread) – no.
• Option D: Solids (definite shape/volume) – no.

Answer:

B. [The option with the liquid - like image (e.g., the one with the blue, fluid - looking picture)]
