Properties of Liquids

Q.

What is the difference between solid and fluid?

Q.

Give examples of the liquid-liquid mixture.

Q.

How are the intermolecular distance and intermolecular forces of attraction related to each other?

Q. Water at room temperature is a liquid but iron piece is a solid because

1. Intermolecular forces between the water molecules are less.

2. Intermolecular forces between the iron molecules are less

3. Intermolecular spaces and kinetic energy among the water molecules are less

4. Intermolecular spaces and kinetic energy among the iron molecules are less

Q.

Differentiate between inter molecular distance and inter-molecular force.

Q.

Why can the molecules in a liquid move freely?

Q.

Water at room temperature is a liquid because

1. All of the above

2. Intermolecular forces between the water molecules are weak.

3. Intermolecular spaces among the water molecules are less.

4. The kinetic energy among the water molecules is less.

1. True

2. False

Q.

What is the force of attraction between the molecules of a substance called?

Q. A definite volume but not a definite shape, is a property of:

1. solid
2. gas
3. liquid
4. all of the above

Q.

2. Tick the most appropriate answer:

(vii) The force of attraction between similar kinds of molecules is called the force of

1. cohesion

2. adhesion

3. molecular attraction

4. none of these

Q.

Which one of the following best describes liquid?

1. No definite volume and no definite shape.

2. Definite shape and volume.

3. Definite volume and no definite shape.

4. Definite shape and no definite volume.

Q.

4. (b) On the basis of molecular theory, explain why liquids have a definite volume, but no definite shape?

Q. If we compress any liquid or gas with tremendous force, will the gas or liquid become a solid ?? (Because tremendous compression will decrease the inter-molecular spaces)

Q. Which of the following characteristics of liquid?
