What is the transferred?
The state of matter with the second lowest energy is this.
What is liquid?
When you touch a hot pan the energy is going from what to what.
what is the pan to your hand?
The term for when a substance goes from one state of matter to another.
What is a state change/phase change?
These are the three main states of matter
What are solids, liquids, and gasses?
How do you make a GAS into a LIQUID?
Remove THERMAL ENERGY
All the kinetic energy of the molecules in an object is known as this.
What is thermal energy?
The law of conservation of energy
What is energy cannot be created or destroyed? Energy can only TRANSFER from one thing to another.
The state of matter with the highest energy state is this.
What is gas?
How do you make a SOLID become a LIQUID?
True or false: Cold is a real thing.
FALSE -cold is just LOW THERMAL ENERGY
Vocabulary - the energy that an object has because it is moving
What happens to energy in DIFFERENT materials?
It changes thermal energy at DIFFERENT rates.
This is happening to the energy in a molecule to make it turn from a liquid into a gas.
What is increasing?
The state of matter with the lowest energy is this.
What is solid?
Vocabulary - a measure of how hot or cold something is
What is temperature?
When two objects ___________ into each other heat is transferred.
What is collide?
When a can of warm sprite is placed in an ice chest full of ice, the thermal energy will flow from this to this.
What is from the can of sprite to the ice?
Cold room will lose energy
Hot room will gain energy
Heat always moves from this to this.
What is hot to cold (high to low)?
Eric pours some iced tea into a glass. When he puts the iced tea in the glass, the energy of THE GLASS decreases. What must be true of the ENERGY of the ICED TEA?
What is the energy INCREASES?
If the glass is decreasing in energy, it is sharing with the iced tea. So, the iced tea is increasing in energy that it is getting from the glass.
A device used to measure temperature is known as this.
What is a thermometer?
Vocabulary - The total kinetic energy of all the molecules that make up a sample.
What is thermal energy?
The average kinetic energy in the molecules of a substance.
