Ice can become a ____________ when its melted.
A liquid can become a _________ when heated to 100c.
Water can become a solid when it is below 0c.
Ice can become a liquid when it is melted.
a liquid can become a gas when heated to 100c.
___________ occurs when a solid becomes a liquid
Melting
A tree is a _______
Solid
What is thermal energy?
Energy in an object due to the movement of its molecules and atoms.
What are the 3 main states of matter, name an example for each
Solid: Holds its shape unless a force is applied (tree)
Liquid: Has no defined shape (water)
Gas: Expands to fit the volume of a container its placed in (water vapour)
The particles in gas follow no ____________. When water is turned to gas, it is called water ___________.
The particles in gas follow no pattern. When water is turned to gas, it is called water vapour.
___________ occurs when a _________ becomes a solid
Freezing, liquid
Helium is a _________ and a stream is a _________
How can you lose thermal energy?
When an object is cooled it loses thermal energy.
All matter is made up of atoms, how are each categorie of matter packed with atoms?
Solids are packed together very tightly.
Liquids are packed together more loosely than solids, but more densely than gases.
Gases have particles that are spread appear and they move freely at high speeds.
A ___________ expands to fill its container. The particles in ________ are __________ spaced. Water will turn to a ________ when it is ______ above 100c.
A gas expands to fill its container. The particles in gas are widely spaced. Water will turn to a gas when it's heated above 100c.
liquid
A pencil is a ___________, water is a ____________, and steam is a ________
solid, liquid, gas
How does an object gain thermal energy?
When an object is heated
____________ is when a solid turns into a gas without passing through the _________ stage.
Sublimation is when a solid turns into a gas without passing through the liquid stage.
A __________ takes the shape of its container. The particles in a ________ are ___________ packed together. When water freezes it becomes a ____________. __________ have a ________ volume but no shape.
A liquid takes the shape of its container. The particles in a liquid are loosely packed together. When water freezes it becomes a solid. Liquids have a fixed volume but no shape.
condensation, liquid
Rain is a __________, snow is a ____________, your breath on a cold winters day is a ___________
liquid, solid, gas
Can you guess what magnetism means
The force that attracts or repels objects made of magnetic material.
__________ is when a gas turns into a _________ without passing through the liquid stage.
Deposition is when a gas turns into a solid without passing through the liquid stage.
A ________ keeps its shape. A __________ particles are in an ________ arrangement. ice will ___________ when its above 0c. When ice melts it becomes a ________.
A solid keeps its shape. A solids particles are in an ordered arrangement. Ice will melt when it's above 0c. When ice melts it becomes a liquid.
___________ occurs when a _________ becomes a __________
sublimation, solid, gas
deposition gas, solid
________ occurs when a solid changes into a liquid.
________ occurs when a liquid changes into a solid
________ occurs when a gas changes into a liquid
________ occurs when a solid changes into a gas
solid --> liquid = Melting
liquid --> solid = Freezing
gas --> liquid = Condensation
solid --> gas = Sublimation
