change of state and physical change + 1
What is a state of change
A state of change is when it's one state of matter then turns into another
What is melting?
the melting particles are when a solid turns into a liquid by absorbing thermal energy.
What is a phase change?
Phase change is when a physical process where transitions between solid, liquid, gas, and plasma.
What is evaporation?
Evaporation is the phase change from liquid to gas which is water vapour.
What is condensation?
Condensation is when gas cools and turns into liquid like water.
What is a physical change
physical change is when it changes its size, shape or state
How does a solid start to change into a liquid?
the melting particles are when a solid turns into a liquid by absorbing thermal energy. this makes the particles pack tightly and gain kinetic energy.
Which states of matter are involved in phase changes?
solid, liquid, gas, and plasma.
What does evaporation turn a liquid into?
Evaporation is the phase change from liquid to gas which is water vapour.
When does condensation happen?
It happens when air reaches the dew point and can’t hold a lot of moisture.
Example in slides for state of change
a examples of state change is when ice melts it turns into water. that is solid turning into a liquid.
What happens to the particles when thermal energy is added?
this makes the particles pack tightly and gain kinetic energy. it also vibrates faster and break free from it original form.
What are some examples of phase changes?
Some examples are melting, freezing, boiling, and condensation.
Where does evaporation occur?
That occurs at the surface when the molecules gain heat energy to overcome the surface tension.
Where do condensation droplets form?
Droplets form on tiny particles like dust or pollen in the air or on windows.
example in slides for physiscal change
like when you put a liquid in a cup it takes the shape of the cup which is shape and size.
What is thermal energy?
Thermal energy is when energy created by the random motion of molecules and atoms.
Which phase change turns a solid into a liquid
Some examples are melting, freezing, boiling, and condensation.
Why do molecules leave the liquid during evaporation
That occurs at the surface when the molecules gain heat energy to overcome the surface tension.
Where does condensation happen naturally
Clouds and fog in the atmosphere, dew on grass and plants in the morning, rain forming inside clouds, mist near lakes, rivers, and oceans, and moist cave walls where humid air cools.

Why do particles break free from their original form during melting?
the melting particles are when a solid turns into a liquid by absorbing thermal energy. this makes the particles pack tightly and gain kinetic energy. it also vibrates faster and break free from it original form.
Name a phase change that makes a gas become a liquid.
Some examples are melting, freezing, boiling, and condensation.
What causes evaporation to happen?
That occurs at the surface when the molecules gain heat energy to overcome the surface tension.
Why do we see dew on grass in the morning?
Because the air cools overnight, reaches the dew point, and can’t hold all its moisture, so water condenses on grass and plants.
