1a. States Of Matter

Question 1

What are the states of matter?

Answer 1

Solid, Liquid, Gas

Question 2

What is solvent?

Answer 2

Substance, ordinarily a liquid, in which other materials dissolve to form a solution

Question 3

What is solute?

Answer 3

The substance that dissolves in a solvent to produce a homogeneous mixture

Question 4

What is solution?

Answer 4

A homogeneous mixture of one or more solutes dissolved in a solvent

Question 5

What is solubility?

Answer 5

The maximum amount of a substance that will dissolve in a given amount of solvent at a specified temperature

Question 6

What is saturated solution?

Answer 6

a solution in which the maximum amount of solvent has been dissolved

Question 7

What is the properties of a solid’s volume and shape?

Answer 7

The volume of a solid is fixed and the shape of a solid is fixed

Question 8

What is the properties of a liquid’s shape and volume?

Answer 8

The volume of a liquid is fixed and the shape of the liquid take the shape of the container

Question 9

What is the properties of gas’s volume and shape?

Answer 9

The volume of a gas is not fixed and the shape of the gas is not fixed.

Question 10

What is melting?

Answer 10

Melting is when a solid is heated and becomes a liquid

Question 11

What is evaporation?

Answer 11

Evaporation is when liquid is heated and becomes gas

Question 12

What is sublimation?

Answer 12

Sublimation is when solid is heated and it becomes a gas

Question 13

What is solidification?

Answer 13

Solidification is when liquid is cooled down and it becomes a solid

Question 14

What is condensation?

Answer 14

Condensation is when gas is cooled down and it becomes a liquid

Question 15

What is deposition?

Answer 15

Deposition is when gas is cooled down and it becomes a solid.

Question 16

Is heat absorbed or released by these processes: condensation, solidification and deposition?

Answer 16

Heat is released

Question 17

Is heat released or absorbed in these processes: evaporation, melting, sublimation

Answer 17

Heat is absorbed

Question 18

What happens at melting point?

Answer 18

Melting is when the strong forces of attraction holding the particles together are broken

Question 19

What happens when liquid evaporating?

Answer 19

Liquid evaporating is when a few particles gain enough energy to escape as a gas

Question 20

What happens to the particles when they are a solid and is being heated up?

Answer 20

Solid - as the temperature rises, the particles begin to vibrate.

Question 21

What happens to the particles when a liquid is being heated up?

Answer 21

Liquid - the forces of attraction are constantly being broken and formed, leading to a less orderly arrangement of particles than in the solid phase.

Question 22

What happens to the particles when the liquid is boiling?

Answer 22

The forces of attraction between teh particles are completely broken and the particles escape as gas.

Question 23

What happens to teh particles when it is above the boiling point?

Answer 23

There is no liquid left. The particles in teh gaseous phase are moving completely randomly and are the least ordinary in their arrangement.

Question 24

What happens to the particles inside a solid?

Answer 24

Particles packed closely, vibrating slightly. A very orderly arrangement held together by the forces between the particles.

Question 25

Why is plasma sometimes considered as the 4th state of matter?

Answer 25

Plasma is a form of matter. It is when electrons wander round freely amount the nuclei of the atoms

Question 26

What is the name of the transition between ice and water?

Answer 26

Melting

Question 27

What is the name of the transition between water and steam?

Answer 27

Evaporation.
