What is the law of conservation of energy
100
transfer of energy through the motion and collision of particles from one substance to another
What is conduction
100
What best represents heat transfer through convection. A)boiling water on an electric stove B) lighting a bulb using a battery and wires C) getting a sun tan D) inflating a hot air balloon
What is D) inflating a hot air balloon
100
Does heat travel from the warmer object to the cooler object or from the cooler object to the warmer object.
What is warmer object to the cooler object.
100
Explain how a thermometer works.
What is the liquid (sometimes colored alcohol but can also be a metallic liquid called mercury.) grow bigger(expand) when heated and smaller(contract) when cooled.
200
the ability to do work or cause change
What is energy
200
A form of potential energy related to the molecular structure of a substance. A new substance will be formed.
What is chemical energy
200
Heat energy is an example of kinetic energy. What is the motion involved in heat energy?
What is the motion of the molecules.
200
What must occur for an object to change phase?
What is an increase or decrease in energy.
200
What is letter e. on the diagram
What is potential energy
300
a physical change in which matter increases in size due to temperature changes.
What is thermal expansion
300
Stored energy
What is potential energy
300
What is letter b. on the diagram?
What is Kinetic and potential energy
300
"Everything is either matter or energy" explain what is meant by this.
What are all things are made up of matter (solid, liquid, gas) and the phenomena on Earth such as heat, light, and sound are types of energy used to change forms of matter or are produced from matter.
300
If you set a top in motion, will the top remain spinning forever? Explain.
What is no, it will come to a stop. The kinetic energy of the top will transfer to heat energy through friction of the table and air resistance.
400
The Law of Conservation of Mass
What is the mass within a closed system remains the same regardless of the energy transformations
400
Energy an object has due to the separation or height above the ground.
What is gravitational potential energy
