Vocabulary 1
The process where water slowly changes from a liquid to a gas and single molecules of water leave the surface to go into the air one at a time.
What is evaporation?
No matter can get in or out of the system
What is a closed system?
Lids, double walls, insulation, and metal.
What are cup features?
Takes up space and can be weighed.
What is matter?
What is thermal energy?
A) The energy stored in the position of objects
B) The energy that causes objects to move
C) The energy of moving particles in matter
D) The energy that is created by sound
What is C) The energy of moving particles in matter?
Matter can get in and out of it through openings in the system
What is open system?
A material that does not allows light to pass through, not transparent
What is opaque?
What is double wall metal?
What is slow?
How does heat transfer between objects with different temperatures?
A) Heat moves from the cooler object to the hotter object
B) Heat moves from the hotter object to the cooler object
C) Heat stays with the object that is colder
D) Heat does not move between objects
What is B) Heat moves from the hotter object to the cooler object?
The transfer of energy from warmer substances to cooler substances.
What is heat?
Measure of average kinetic energy of particles in a substance
What is temperature?
What is air or gas?
This is how particles move in hot liquid.
What is fast?
Which of the following is an example of thermal energy transfer through radiation?
A) Boiling water in a pot
B) The warmth from the sun reaching Earth
C) A spoon becoming hot in soup
D) Ice melting in a warm room
What is B) The warmth from the sun reaching Earth?
When light transfers energy into particles.
What is absorbtion?
Motion of particles in a substance
What is thermal energy?
Because of this water was heating up even in a closed system.
What is light energy?
These are the three states of matter.
What is solid, liquid and gas?
Which of the following is an example of heat transfer by conduction?
A) A metal spoon getting hot after being placed in a pot of soup
B) Warm air rising from a heater
C) Water boiling in a pot
D) Heat from the sun warming the Earth’s surface
What is A) A metal spoon getting hot after being placed in a pot of soup?
The energy of movement
What is kinetic Energy?
When thermal energy is transferred via particle collisions
What is conduction?
What is the surface of the cup?
When a liquid gets enough energy it will do this.
What is evaporate?

A) Conduction
B) Radiation
C) Convection
D) Insulation
What is C) Convection
