Question 1:

Which of the following statements is true about the arrangement of particles in a liquid state?

A) The particles are closely packed in a regular arrangement
B) The particles are loosely packed and have significant empty space
C) The particles are free to move around randomly
D) The particles are in a gaseous state

Show Answer

Explanation: The correct answer is C) The particles are free to move around randomly. In the liquid state, the particles are close together but do not have a regular arrangement. They are able to move around randomly, allowing liquids to flow and take the shape of their container.

Question 2:

Which of the following properties is characteristic of liquids?

A) Definite shape and volume
B) Indefinite shape and definite volume
C) Indefinite shape and volume
D) Definite shape and indefinite volume

Show Answer

Explanation: The correct answer is B) Indefinite shape and definite volume. Liquids do not have a definite shape and can take the shape of their container. However, they have a definite volume, meaning they have a fixed amount of substance regardless of the container's shape.

Question 3:

Which of the following describes the motion of particles in a liquid state?

A) Vibrational motion around fixed positions
B) Random translational motion
C) Rapid movement with large distances between particles
D) Constant expansion and contraction

Show Answer

Explanation: The correct answer is B) Random translational motion. In the liquid state, the particles have random translational motion, meaning they move around randomly but remain close to each other. The particles can slide past one another, allowing liquids to flow.

Question 4:

Which of the following is an example of a liquid?

A) Oxygen gas
B) Steel
C) Mercury
D) Diamond

Show Answer

Explanation: The correct answer is C) Mercury. Mercury is an example of a liquid at room temperature. Liquids can exist at various temperatures and exhibit fluidity, allowing them to flow and take the shape of their container.

Question 5:

Which of the following is a property of liquids?

A) Low density
B) High compressibility
C) Undefined boiling point
D) Variable volume

Show Answer

Explanation: The correct answer is D) Variable volume. Liquids have variable volumes, meaning their volume can change depending on the container they are placed in. However, liquids have a relatively high density, low compressibility, and a defined boiling point.
