These are found in the center of an atom along with the neutrons.
Hint: Positive charge
What are Protons?
What is done when a force is applied to an object as it moves through a distance
What is WORK
Matter that is made up of molecules that are not as tightly packed as solids. This state of matter takes the shape of whatever container it is in.
What is a liquid?
Ice being solid enough to ice skate on is an example of this state of matter
What is a freezing?
A science tool used to measure the volume of liquids.
What is a graduated cylinder?
Changes that can go back to the original form.
What is reversible change?
These have a negative charge and are found in the space around the protons and neutrons in an atom.
DOUBLE JEOPARDY
What are electrons?
A substance made up of 2 or more different elements.
What is a compound?
Matter that is made up of molecules that are loosely packed that move around. This type of matter also takes up the shape of whatever container they are in. This type of matter is often invisible.
What is a gas?
Dew is a result of water vapor making this change from a gas to a liquid
What is a condensing?
The relationship between mass and volume of an object. (mathematically calculated V= M/V)
What is density?
Which are the chemical changes:
1-Baking a cake 2-Butter melting
3-A log burning 4-Film canister rockets
5-Paper being torn 6-fireworks exploding
What is 1, 3, 4, and 6?
What are neutrons?
A compound is made up of these in the same proportions
What are elements?
Matter that is made up of tightly packed molecules that have a definite shape.
What is a solid?
Boiling is a an example of state of matter change from liquid to gas
What is vaporization?
A characteristics of matter that can be measured and helps describe it. (Shape, size, color, hardness, density, volume, mass, texture)
DOUBLE JEOPARDY
What is property?
Changes that can not go back to the original form.
What is a irreversible change?
A combination of elements bonded together.
What is a molecule?
What is the chemical formula for carbon dioxide?
What is CO2?
A pure substance that CANNOT be broken down chemically
What are elements?
A substance's state of matter is most directly affected by this
What is temperature?
transforming something from one substance to another, like the burning of paper or rusting of metal
What is a chemical change?
When chemical changes take place, no new matter is produced or destroyed; molecules are just moved around to create new substances.
DOUBLE JEOPARDY
What is Law of Conservation of Matter?
This is where fission or fusion takes place in an atom (choose between center with protons/neutrons, or orbital with electrons)
What is the center?
