Physical/Chemical Change
A change to a substance's state of matter but not its chemical material.
What is a Physical Change?
This theory states that "Matter cannot be created nor destroyed".
What is the Law of Conservation of Mass?
I am on the outer layers of an atom and have a negative charge.
What are Electrons?
I am malleable and highly conductive.
What is a Metal?
Molecules are tightly packed in this form.
What is a Solid?
A change to a substance that completely alters its identity.
What is a Chemical Change?
Melting water in any container.
An example of the Law of Conservation of Mass.
I am part of an atom's nucleus and have a positive charge.
What is a Proton?
I am not malleable and have poor conductivity.
What are Nonmetals?
A transition from a Liquid to a Solid.
What does it mean to Freeze?
I am one of the most commonly examples of a chemical change.
What is burning wood considered?
This scientist formulated the Law of Conservation of Mass.
"Who is Antoine Lavoisier?"
I am part of an atom's nucleus and have a neutral charge.
What is a Neutron?
I am somewhat malleable and semi-conductive.
What are Metalloids?
What is Plasma?
I am one of the most commonly used substances in demonstrating a physical change.
What is H2O/Water?
This type of system can best simulate/demonstrate the Law of Conservation of Mass.
What is a Closed System?
This is where an atom's valence electrons are located.
What is the outermost layer of an atom?
I can be flattened with a hammer and considered durable.
What does it mean to be malleable?
Molecules in this state have a definite volume, but have an indefinite shape.
What is a Liquid?
I am evidence of either changes occuring.
What is a form change?
What year was the Law of Conservation of Mass formulated?
1789
This is where protons and neutrons reside in an atom.
What is an atom's nucleus?
I can be (physically) broken into pieces easily.
What does it mean to be brittle?
The temperature needed to cause a substance to melt.
What is a Melting Point?
