Question

Substance X has a fixed volume, and the attraction between its particles is strong. Substance Y has widely spread out particles and can be compressed. What can most likely be concluded about these substances?


A) Substance X is a crystal, and substance Y is a liquid.
B) Substance X is a gas, and substance Y is a plasma.
C) Substance X is a plasma, and substance Y is a crystal.
D) Substance X is a solid, and substance Y is a plasma.

Answer 1

Answer: D) Substance X is a solid, and substance Y is a plasma.

Explanation: Solid is the state of matter in which particles have strongest forces of attraction. They have no vacant spaces between the particles and thus cannot be compressed. The volume and shape of the solids is fixed.

Liquid is the state of matter in which particles have weak forces of attraction. They have vacant spaces between the particles. The volume of liquids is fixed and they acquire the shape of the container.

Gas is the state of matter in which particles have weakest forces of attraction.They have large vacant spaces between the particles and thus can be compressed on applying force. The volume and shape of gases is not fixed.

Plasma is the state of matter which consists of ionized gas at high temperature. Thus have large vacant spaces between the particles and thus can be compressed on applying force. The volume and shape of plasma is not fixed.

Answer 2

Answer:

D.  Substance X is a solid, and substance Y is a plasma.
