These are the 3 states of matter.
What are solid, liquid and gas?
The middle of the atom that includes Protons and Neutrons
What is the nucleus?
Baking cookies & bicycle rust are both examples of...
This is any process in which the system loses heat to the environment.
What is exothermic?
In a chemical reaction, this is the amount of mass that will be lost.
What is zero?
In this state of matter, the molecules vibrate fast, but do not have room to move past each other easily.
What is a solid?
This is the positive subatomic particle of an atom.
What is the proton?
Mixing Lemonade is a good example of what kind of reaction?
What is physical?
In this type of reaction, the environment's temperature decreases because the reaction has absorbed energy from the environment.
What is endothermic?
These are the two subatomic particles that contain most of the atom's mass.
What are protons and neutrons?
In this state of matter, the molecules move the fastest, spreading out into all the space available.
What is a gas?
These subatomic particles orbit the nucleus and have a negative charge.
What are electrons?
Molecules and compounds are both formed in these kinds of reactions.
What is chemical?
This type of potential energy is stored in the bonds of atoms and molecules.
What is chemical potential energy?
This is a measure the amount of mass in a given volume; measured in kilograms per meters cubed.
What is density?
The states of matter describe this kind of property.
What is a physical property?
An element is determined by the number of these? This is also known same the atomic number of the element.
What are protons?
These produce the "product" in a chemical reaction.
What are reactants?
This type of energy determines whether or not something is a solid, liquid or gas.
What is thermal energy?
Mass is always measured in this standard unit.
What are kilograms?
This material is unlike any material on Earth. It is often considered a "rigid liquid" because it isn't quite a solid and not quite a liquid.
What is glass?
In the element of Magnesium, this shell is considered "unfulfilled". The Letters of these shells are K, L, & M, respectively.
What is shell "M" (the 3rd shell) in the element of Magnesium?
This is a combination of two or more different elements bonded together.
What is a compound?
When you cook an egg, you heat up a pan. The egg absorbs thermal energy from the pan as it cooks. The cooked egg has different properties from the raw egg. This describes the PROCESS that cooks the egg.
What is an endothermic reaction?
Unlike mass which does not change with location, this measurement is associated with the gravitational force exerted on an object. It is always measured in Newtons.
What is weight?
