Matter
This subatomic particle determines the identity of an element.
What is a proton?
What type of energy is the energy of motion determined by 1/2 mass x velocity?
What is kinetic energy?
Heat transfer through direct contact.
What is conduction?
The formula for determining the speed of an object.
What is distance divided by time?
According to the Law of Conservation of Matter, this must remain the same in a chemical reaction.
What is the # and type of atoms OR?
What is the mass?
A substance that has a fixed composition and cannot be separated by physical means.
What is a pure substance?
Energy stored due to position or shape.
What is potential energy?
Heat transfer by movement of fluids.
What is convection?
What is direction?
When kinetic energy decreases due to friction, it gives off this type of energy.
What is heat or thermal energy?
A student observes bubbles forming and a temperature change. This type of change has occurred.
What is chemical change?
The energy transformation in a flashlight when it is turned on.
What is chemical to electrical to light and heat?
Heat always moves in this direction.
What is warmer to cooler?
This is needed to describe an object’s position.
What is reference point?
Elements in the same column on the periodic table share this.
What is valence electrons? OR
What is similar chemical properties?
This type of mixture is physically combined and has a uniform composition that can be separted by physical means.
What is a homogeneous mixture?
This law states that energy cannot be created or destroyed, only transformed.
Heat transfer through space/ electromagnetic waves.
What is radiation?
On a speed-time graph, a flat horizontal line shows this type of motion.
What is constant speed?
The periodic table is arranged by increasing this value.
What is atomic number OR number of protons?
This property tells how much mass is in a given volume.
What is density?
A roller coaster car has the most potential energy at this location.
What do air particles do when heat is added through convection?
An object can accelerate even if its speed stays the same by doing this.
What is it changes direction?
On a DISTANCE/TIME graph, this is happening when you see a horizontal line.
What is no movement?
