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
The ice floats on water because
its density is more than water
its density is less than water
it has intermolecular space
none of the above
Anything that occupies space and has mass is known as
Object
Subject
Matter
Weight
The conversion of gas into liquid is called
freezing
condensation
sublimation
fusion
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 diagram shows the changes in state of water (H2O). What is the process W called?
Condensation
Melting
Freezing
Boiling
Dry ice is used in fire extinguishers. The dry ice is stored in the cylinder in a solid form. When sprayed on a fire it quickly changes into the gas known as carbon dioxide (CO2). What is this change of state called?
Sublimation
Evaporation
Distillation
