The boiling point of a substance is the temperature at which it changes from
a liquid to a solid
a gas to a solid
a solid to a liquid
a liquid to a gas
When a gas is compressed it changes its state into a
plasma
vapour
liquid
solid
The force that binds the particles of matter together is known as
nuclear force
intermolecular force
internal force
binding force
Sublimation occurs when
a gas changes into a solid
a solid changes into a liquid
a liquid changes into a gas
a solid changes into a gas
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
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 density of water is maximum at
0°C
100°C
4°C

When two gases mix together, they are said to
evaporate
condense
diffuse
melt
