Phase Changes
What is evaporation?
Liquid to gas
How do you increase the particle movement of an object?
Add energy to it
How do solid molecules move?
Slowly in place (low kinetic energy)
What state of matter is A?
Solid
How do we achieve a phase change?
Adding energy
What is freezing?
Liquid to solid
If I am putting water into the freezer, what is happening to the energy and particle movement
Energy and particle movement is decreasing.
How do liquid molecules move?
What state of matter is C?
Liquid
Why did the food coloring spread faster in the hot beaker?
The molecules were moving faster in the hot beaker.
What is melting?
Solid to liquid
How does heat flow?
Hot to cold
How do gas molecules move?
Very fast and far away (high kinetic energy)
What state of matter is E?
gas
Losing since it is going from a gas to liquid (molecules are moving slower)
What is condensation?
If I am boiling water, describe what is happening to the water molecules
The molecules are moving faster until they go through a phase change.
solid, liquid, gas
What is happening during B and D?
A phase change
Is an objecting losing or gaining energy when it is going through evaporation?
Gaining, its going from a liquid to gas (molecules are moving faster)
What is sublimation?
Solid to gas
Create a sentence explaining the connection between energy, temperature and particle movement
Put the states of matter in order of decreasing kinetic energy?
gas, liquid, solid
Why does the energy not increase during a phase change?
The added energy is being used to break the molecular bonds.
If the temperature of an object increases, what is happening to the amount of energy?
Increase in energy
