Answer 11

There are strong forces of attraction between the particles of liquid.

Question 12

Describe the forces of attraction between the particles of gas.

Answer 12

The forces of attraction between the particles of gas are negligible.

Question 13

Explain why solid has a fixed shape. (using kinetic model of matter)

Answer 13

Particles of solid are arranged in an orderly manner and can only vibrate vigorously at fixed positions.

Question 14

Explain why liquid does not have a fixed shape. (using kinetic model of matter)

Answer 14

Particles of liquid does not have a fixed arrangement and can slide past each other over short distances.

Question 15

Explain why gas does not have a fixed shape. (using kinetic model of matter)

Answer 15

Particles of gas does not have a fixed arrangement and can move freely and randomly at high speeds.

Question 16

Explain why solid has a fixed volume. (using kinetic model of matter)

Answer 16

Particles of solid are packed closely together and they have strong forces of attraction between them.

Question 17

Explain why liquid has a fixed volume. (using kinetic model of matter)

Answer 17

Particles of liquid are packed closely together and they have strong forces of attraction between them.

Question 18

Explain why gas does not have a fixed volume. (using kinetic model of matter)

Answer 18

Particles of gas are far apart from one another and forces of attraction between them are negligible.

Question 19

Explain why solid cannot be compressed. (using kinetic model of matter)

Answer 19

Particles of solid are packed closely together and they have strong forces of attraction between them. Therefore there is no space in between the particles of solid to move closer to one another.

Question 20

Explain why liquid cannot be compressed. (using kinetic model of matter)

Answer 20

Particles of liquid are packed closely together and they have strong forces of attraction between them. Therefore there is no space in between the particles of liquid to move closer to one another.

Question 21

Explain why gas can be compressed. (using kinetic model of matter)

Answer 21

Particles of gas are far apart from one another and forces of attraction between them are negligible. Therefore there is space in between the particles of gas to move closer to one another.

Question 22

Explain why solid cannot be flow. (using kinetic model of matter)

Answer 22

Particles of solid have a fixed arrangement and can only vibrate at fixed positions.

Question 23

Explain why liquid can be flow. (using kinetic model of matter)

Answer 23

Particles of liquid does not have a fixed arrangement. and can slide past each other over short distances.

Question 24

Explain why gas can be flow. (using kinetic model of matter)

Answer 24

Particles of gas does not have a fixed arrangement. and can move freely and randomly at high speeds.

Question 25

Describe what changes occurs to the movement of the particles of solid when the solid is heated.

Answer 25

Particles of solid would vibrate more vigorously at fixed positions.

Question 26

Describe what changes occurs to the movement of the particles of liquid when the liquid is heated.

Answer 26

Particles of liquid would slide past each other faster over short distances.

Question 27

Describe what changes occurs to the movement of the particles of gas when the gas is heated.

Answer 27

Particles of gas would move freely and randomly at higher speeds.
