Studied by 29 peopleThe phase change of a substance from the liquid state to a solid- state is called ________.
freezing
If the surface area is increased, the rate of evaporation ________.
increases
________ is the change of gaseous state directly to solid state without going through liquid state.
Deposition
________ is the change of solid state directly to gaseous state without going through liquid state.
Sublimation
Although they are not rigid, fluids can change shape and flow.Intermolecular space is more than solids and ________ is less than solids.
intermolecular force of attraction
DRY ICE
________- When the pressure is reduced to one atmosphere, solid CO2 is immediately transformed to a gaseous state without first entering a liquid state.
________ drops as a result of the water vapour particles being carried away by the wind as wind speed increases, also rate of evaporation is directly proportional to increase in wind speed.
Humidity
Liquids
________ can diffuse solids, ________, and gases.
particles
The forces of attraction between the ________ are defeated by the energy provided by heat.
liquid particles
To make up for the energy lost during evaporation, the ________ take energy from their surroundings.
A drop in humidity: The amount of ________ in the air is referred to as humidity.
water vapour
The particles begin vibrating faster as a result of the increase in ________.
kinetic energy
The particles of matter are very small
they are small beyond our imagination
A rise in temperature
with a rise in temperature,more particles have enough kinetic energy to enter the vapour state as a result of rising temperatures so rate of evaporation increases
a drop in humidity
The amount of water vapour in the air is referred to as humidity
a rise in wind speed
It is a well-known phenomenon that clothes dry more quickly on windy days
________ is anything that has mass and takes up space. It can exist in three states: solid, liquid, or gas.
Matter

metals
The particles that make up matter is ________
atoms
______ is a state of matter has definite shape and size

Evaporation happens when temparature ________
rises
