States of Matter
How many states of matter do we typically see on earth?
3
What do you add or remove for atoms to change state?
Heat or energy.
What is heat?
What is the common name for this ?
The average of the kinetic energy in an object.
Temperature.
How many types of heat transfer do we see on earth?
3
What is the 4th state of matter in the universe?
Plasma
What are the 3 states of matter that we typically see on earth?
Solid, Liquid, Gas
What are the two basic changes of state called when you add heat to a solid and then a liquid?
Melting, evapration.
How does heat change?
Adding or removing energy.
What are the types of heat transfer on earth?
Conduction, Convection, Radiation
Why can heat transfer via radiation transfer through space?
Rays do not need material to travel through, and can therefore travel through the vacuum of space.
This state of matter has no defined shape or mass.
Gas
What are the two basic changes of state when you take energy from gases and then liquids?
Condensation, Freezing.
Are the atoms in a solid moving or still?
Moving, barely.
What is conduction?
Heat Transfer by direct touch.
Radiation to send heat to the Earth, Conduction from the ground heating the air, and then air rising when it heats up through Convection.
This state of matter has a defined shape and a defined mass.
Solid
What is the change of state from a solid directly to a gas?
Sublimation
Heat moves from ______ things to _______ things.
What is Radiation?
Heat transfer by waves or rays.
What are the 3 temperature scales you might see in science?
Farenheight, Celsius, and Kelvin
This state of matter has a defined mass, but no defined shape.
Liquid.
What is the change of state from a gas directly to a solid?
Deposition.
Heat moves to become the ______ in both objects.
the same.
What is Convection?
Heat transfer in a liquid or gas where hot material rises, and cold materials sink, in a circular motion.
What makes plasma, plasma?
There atoms become ionized, having positive charge instead of neutral charge.
