Chemistry Test Rev.

Review for my Chemistry Test

Define Matter Something that takes up space
What is the difference between intrinsic and extrinsic properties? Intrinsic = The property will not change depending on how much of an object you have(density/temperature). Extrinsic = will change depending on how much of the object you have (mass, volume).
Define density How much mass there is for the volume of an object.
Difference Between: A) Elements and Compounds B) Ionic and Covalent Compounds A) An element is one pure substance, whereas a compound is a combination of a couple of elements. B)Ionic Bond: Bond between two ions of opposite charge Covalent Bond: Chemical bond created when two atoms share electrons
Difference Between: A) Compounds and Mixtures B) Heterogeneous and Homogeneous Mixtures A) Compounds are combined chemically, whereas mixtures are combined physically B)In Homogeneous Mixtures you can't tell what all of the components are, whereas in a Heterogeneous Mixtures, you can.
List 4 ways you can separate solids from liquids. - Filtration - Evaporation - Centrifugation - Crystallization
List 2 ways you can seperate two solids. - Filtration - Dissolution
How do you seperate liquids? Distillation
Describe the differences in the three states of matter. Solids: Strong bonds, atoms only vibrate a little and don't move around much Liquids: Weaker bonds than solids, have a little bit of space to move around in. Gases: Very weak bonds, they move around freely in their container
Differentiate kinetic energy from potential energy. Kinetic energy is when something is moving, potential energy is when something has the potential to move, but isn't yet.
Describe the kinetic molecular theory. - All matter is made of atoms - Particles move all the time - Heavier particles move slower than lighter ones
Describe Melting/Freezing The temperature has hit the melting/freezing point, and now the bonds of the solid are weakened/strengthened, to form a liquid/solid.
Describe Boiling The liquid has hit its boiling point, and now, like at its melting point, the bonds are weakened further, to create a gas.
Describe Condensation A gas hits a cold surface, which quickly changes the particles into liquid particles.
Another word for temperature? Average Kinetic Energy
What happens to particles during sublimation? In sublimation, particles rapidly spread out.
How much is 0 degrees Celcius in Kelvin? 273 Kelvin
How is the volume of a gas affected by the temperature of the gas? By heating/cooling a gas, the particles gain/lose energy. Therefore they hit more/less frequently against their container causing an increase/decrease in volume.
State Charles' Law. When the temperature of a gas is increased, the volume will increase as well.
State Boyle's Law. When the pressure of a gas is increased, the volume will decrease.
