Name the interconversion that takes place when a liquid becomes a solid.
The interconversion that takes place when a liquid becomes a solid is called freezing.
What type of energy allows particles to move in the liquid state?
The type of energy that allows particles to move in the liquid state is kinetic energy.
State what is meant by sublimation.
Sublimation is when a solid changes directly into a gas.
Which state of matter has particles very close together that vibrate about a fixed position?
The solid state state has particles very close together that vibrate about a fixed position.
True or False?
Particles in a liquid move quickly in all directions.
False.
Particles in a liquid have restricted movement and move around each other. Gas particles move quickly in all directions.
True or False?
Energy is needed to change a gas to a liquid.
False.
Energy is released when a gas changes into a liquid.
True or False?
The melting point and freezing point of a substance are the same.
True.
There is no difference between the melting point and freezing point.
What happens to the forces of attraction when a solid turns to a liquid?
When a solid turns to a liquid, the forces of attraction are overcome or broken.
True or False?
The three states of matter are solids, liquids and gases.
True.
The three states of matter are solids, liquids and gases.
What is melting?
Melting is when a solid changes into a liquid.
What is boiling?
Boiling is when a liquid changes into a gas.
What is freezing?
Freezing is when a liquid changes into a solid.
What is evaporation?
Evaporation is when a liquid changes into a gas.
What is condensation?
Condensation is when a gas changes into a liquid, usually on cooling.
What does the term interconversion of state mean?
Interconversion of state is the change of matter from one state to another due to changes in temperature or pressure.
