Equal volumes of all gases under similar conditions of temperature and pressure contain equal numbers of molecules. This statement was made by
John Dalton

Study the diagram carefully. It shows the way that the particles of a solid occupies space. The particles of a solid are packed closely together and cannot move around but they can vibrate.Select the property of a solid from the list below, which is consistent with (matches) this micro-view of this state of matter.
No definite volume
Cannot be compressed
Can flow
No definite shape
The conversion of gas into liquid is called
freezing
condensation
sublimation
fusion
The diagram shows the changes in state of water (H2O). What is the process X called?
Evaporation
Freezing
Melting
Boiling
The diagram shows the changes in state of water (H2O). What is the process W called?
Condensation
Cooking of rice at higher altitudes is difficult because
water boils at 100°C
water boils at
boiling point of water is constant
none of the above
When the temperature of a liquid is increased a little, what happens to its particles?
They stop vibrating.
They move so far apart that the liquid becomes a gas.
They start vibrating more.
They come closer together.
The force that binds the particles of matter together is known as
nuclear force
intermolecular force
internal force
binding force
