Solid State

Q.

Why does ice float on water?

Q.

Why do solids have fixed shape and volume

Q.

Solids have a definite shape but not liquids. Why?

Q.

Gases have highest rate of diffusion among all the three states of matter.

1. False

2. True

Q.

Why does ice float on water?

Q.

Define diffusion explain the rate of order of diffusion in solids liquids and gases and state the effect of temperature on diffusion

Q. Why do solids have regular geometrical shape?

Q.

Give examples of diffusion of gas into solid

Q.

Why is the solid state the most dense state of matter ?

Q.

Two factors which determine the rate of diffusion of a liquid in another liquid

Q.

A rubber band can change its shape on stretching will you classify as solid or not

Q.

A wooden table should be called a solid why?

Q. Ice floats over the surface of water because

1. its density is less than that of water
2. its density is more than that of water
3. its molecules are closely packed and no vacant spaces are there
4. its molecules are held together by strong forces of attraction

Q.

If a solid of the same density as that of a liquid is placed in it, what will happen to the solid?

Q.

Why do solids not flow ?

Q. Assertion [A]: A brick has a definite shape.
Reason [R]: Solids have strong intermolecular force of attraction between their particles.

1. Both [A] and [R] are incorrect
2. [A] is correct, but [R] is incorrect
3. Both [A] and [R] are correct
4. [A] is incorrect, but [R] is correct

Q.

A wooden table should be called a solid. Why? [1 MARK]

Q.

why a wooden table should be called a solid

Q. Why diffusion occurs more quickly in gases?

Q. The rate of diffusion in solids is greater than that in liquids.

1. True
2. False

Q. The substances in the solid state generally have

1. 
   fixed volume
2. 
   fixed shape
3. 
   compressible in nature
4. 
   strong intermolecular forces

Q.

Solids have a definite volume but do not have a definite shape.

1. True

2. False

Q.

Solids are the least rigid.

1. True
2. False

Q.

Give a reason for solids are hard and rigid.

Q.

Mention the properties of solid

Q.

How would you explain that iron is solid?

Q.

Which of the following are more denser than the others?

1. Solids

2. Liquids

3. Gases

4. All of these have same densities

Q. Which of the below mentioned options is a set of solid objects?

1. Rubber band, sugar, sponge
2. Sugar, milk, sponge
3. Rubber band, milk, sponge
4. Milk, sponge, soap foam

Q. A sponge is compressible and hence, its not a solid.

1. True
2. False

Q.

Solids do not flow but can be

1. compressed

2. not kept in a container

3. heaped

4. liquefied
