Atoms and elements
Are the atoms in an Element the same or different?
The same
If something gains energy, does it get warmer or cooler?
It gets warmer.
If you touch something hot, what kind of heat transfer is that?
Conduction
Do you have potential or kinetic energy if you are going down a hill?
Both
Do protons have a positive, negative, or no charge?
Protons have a positive charge.
How does water change into a solid?
It loses energy.
In floor heating is an example of what heat transfer?
Conduction and convection.
Does the total energy change or remain the same?
It remains the same.
Do electrons have a positive, negative, or no charge?
Electrons have a negative charge.
How does water change into a gas?
It gains energy
A campfire is an example of what heat transfer if you're sitting beside it?
Radiation
If you are in midair and you are not moving very fast, do you have more kinetic or potential energy?
Potential energy.
Do neutrons have a positive, negative, or no charge?
Neutrons have no charge.
Why doesn’t a solid change shape?
The atoms are packed too tightly together.
If you touch something hot it is a form of conduction.
True
If you are running on flat ground, do you have more kinetic or potential energy?
Kinetic energy.
What is an atom called if it has more protons than electrons or more electrons than protons?
An ion
Why can a liquid change shape?
The atoms have enough space to move.
If you are beside a stove and you feel the heat, it is a form of convection.
False
Does energy ever disappear or appear?
It does not.
