Molecular Structure
100
The building blocks of all things. All matter is made from this.
What are particles?
100
Define thermal energy
The sum of the kinetic energy plus the potential energy of particles in matter.
100
This is the amount of force applied to an object's surface
Pressure
100
Define compound
A compound is two or more different elements bonded together
200
True or False: Elements are moving in gases, liquids, and solids
True
200
This state has the most energy
Gases
200
How does pressure change when temperature changes?
Heating increases pressure and cooling decreases pressure when volume is the same
200
This is something made up of only one type of atom
Elements
300
These are the element symbols for Helium, Oxygen, and Carbon
He, O, C
300
Thermal energy flow from an area of
High temperature (hot) to low temperature (cold)
300
How does the pressure change when the volume changes?
If the volume decreases, then the pressure increases. If the volume increases, then pressure decreases.
300
This is a category of elements that is shiny, malleable, are good conductors, and are mostly solid at room temperature. Elements in this category include, Iron, Copper, and Lead
Metals
400
How many elements can you find in C6H12O6?
3 elements (Carbon, Hydrogen, and Oxygen)
400
This is when the volume of something decreases as temperature decreases
Thermal contraction
400
Pressure is caused by
The force between particles colliding with the container
400
This state of matter cannot be compressed, does not change volume, and its particles have less energy than other states of matter.
Solids
500
What is the formala for this model?
NH4
500
This is when the volume of something increases as the temperature increases.
Thermal expansion.
500
Explain how pressure changes as you go deeper in water
Pressure increases
500
How does the kinetic energy and potential energy of water change as it goes from liquid to solid?
The kinetic energy decreases, and the potential energy increases
