Matter
These are the 3 types of Matter
Liquid, Gas, Solid
The temperature at which a liquid becomes a gas is called the _______
What is the boiling point?
This law states that the volume of a gas increases with increasing temperature, if the pressure in constant.
What is Charles's Law?
In a chemical formula, the number of each type of atom in the compound is shown with numbers that are ____.
What are subscripts?
Adding thermal energy to snow would cause it to _______
What is melt?
This changes the state of matter
Temperature
The evaporation of water is an example of a change in ________.
What is state?
This is a decrease in a material’s volume when the temperature is decreased.
What is Thermal Contraction?
Nonmetals gases are gases at room temperature, since they are composed of individual atoms or small molecules.
True or False
True
The change in state from a gas to a liquid is called __________.
What is condensation?
A change in the state of matter is caused if enough _____ is added to or removed from an object.
What is thermal energy
During a hot shower, water vapor fogs up the cooler mirror when it turns to water. This is an example of _____.
What is condensation?
This is an increase in a material’s volume when the temperature is increased.
What is Thermal Expansion
The molecules in water are farther apart than the molecules in ice. Therefore, the molecules in water have more ________________ than the molecules in ice.
What is Potential Energy?
When the forces of attraction between particles are strong enough to draw particles together and keep them in place, it is called a ___________ state of matter.
What is a solid?
The energy an object has due to its motion
(A ball rolling across a floor)
What is Kinetic Energy
George put a pot of water on to boil eggs. After a few minutes, all the water was gone. This is an example of _____.
What is Vaporization?
This is the amount of force per unit area applied to an object’s surface.
What is pressure?
In general, metals are good conductors of heat, since they are composed of individual atoms or small molecules.
True or False
What is True?
The sum of all the potential energy and kinetic energy of an object equals its _____.
What is thermal energy?
This is stored energy due to the interactions between particles or objects.
What is potential energy?
This is the transfer of thermal energy from a region of higher temperature to a region of lower temperature
What is heat?
In a gas, which quantities relate in such a way that when one increases, the other one decreases? (Think of the syringe filled with air and it being capped)
What is volume and pressure?
Aspartame is an artificial sweetener; its formula is C13H16N2O5. What element in the formula has the most number of atoms?
C-Carbon, H-Hydrogen, N-Nitrogen, O-Oxygen
What is Hydrogen?
In which state of matter are there very weak or no attractions between particles?
What is a gas?
