state of matter

Question 1

solid

Answer 1

Gases have neither definite shape nor definite volume. They expand to the size of their container.
•Gases are fluid, and flow easily.
•Gases have low density, unless compressed. …
•Gases diffuse (mix and spread out) and effuse (travel through small holes).

Question 2

liquid

Answer 2

• Liquids have fixed volume but no fixed shape. They have fixed volume but they do not have fixed or definite shape. …
• Liquids flow from higher to lower level.
• Liquids have their boiling points above room temperature, under normal conditions.

Question 3

gases

Answer 3

Gas is a state of matter that has no fixed shape and no fixed volume. Gases have lower density than other states of matter, such as solids and liquids

Question 4

what is diffusion

Answer 4

Diffusion is the net movement of molecules or atoms from a region of high concentration to a region of low concentration

Question 5

increasing the temperature does

Answer 5

when you increase the temperature it makes the particles move faster. they have two effects:
they hit the walls harder
they hit the walls more often

Question 6

reducing the volume does

Answer 6

when you reduce the volume it increases pressure. this is because when the particles are squashed up into a smaller space they will hit the walls more often

Question 7

At room temperature, what state is mercury in

Answer 7

Mercury is the only metal element that is liquid at room temperature.

Question 8

Which state can be compressed or squashed easily?

Answer 8

A gas can be compressed or squashed easily

Question 9

what state of matter has the most energy in them

Answer 9

it is gases because gases are don’t have a definite volume which means they are allowed to freely move
