| indefinite shape and volume | gas
🗑
|
||||
| a fixed amount of gas at a constant temperature, the volume of the gas increased as the gas' pressure decreases. likewise the volume of the gas decreases as the gas' pressure increases | Boyle's law
🗑
|
||||
| The pressure of a gas increases as the temperature increases, if the volume of the gas does not change. The pressure decreases a the temperature decreases. | Gay-Lussac's law
🗑
|
||||
| For a fixed amount of gas at a constant pressure, the volume of the gas increases as the gas' temperature increases. Likewise, the volume of the gas decreases as the gas' temperature decreases. | Charles' law

| Matter is made of atoms and molecules. Atoms and molecules act like tiny particles that are always in motion | Kinetic theory
🗑
|
||||
| the most common state of matter in the UNIVERSE. 99% of all known matter (sun stars) | plasma
🗑
|
||||
| the buoyant force on an object is a fluid on an upward force equals to the weight of the fluid that the object displaces. the greater the buoyant force, the more it will float | Archimede's principle
🗑
|
||||
| if the pressure in a container is increased at any point, the pressure increases at all points by the same amount. | pascal's principle
🗑
|
||||
| as the speed of a moving fluid increases, the pressure of the moving fluid decreases | Bernoulli's principle
🗑
|
||||
| a liquid's resistance to flow. the stronger the attraction between a liquid's particles is, the more _______ the liquid is. | viscosity/viscous
🗑
|
||||
| the amount of force exerted per unit area of a surface | pressure
🗑
|
||||
| components are evenly distributed. the mixture is the same throughout. | homogeneous mixtures
🗑
|
||||
| the substances is this are not evenly distributed. | heterogeneous mixtures
🗑
|
||||
| able to be mixed | miscible liquids
🗑
|
||||
| not able to be mixed together | immiscible liquids
🗑
|
||||
| a matter that has a fixed composition and definite properties | pure substances
🗑
|
||||
| a combination of substances that are not chemically combined | mixtures
🗑

🗑
|
||||
| a substance made up of atoms of two or more different elements joined by chemical bonds | compounds
🗑
|
||||
| shape and mass are examples some other ones are color, volume, and texture. | physical properties
🗑
|
||||
| this describes how a substance changes into a new substance, either by combining with other elements or by breaking apart into new substances. | chemical properties
🗑
|
||||
| the measure of average kinetic energy. is not determined by how much of a substance you have . the more kinetic energy the higher this is | temperature
🗑
|
||||
| total kinetic energy of a substance's atoms | thermal energy
🗑
|
||||
| Energy may change form during a chemical/physical change, but the total amount of energy remains the same. | law of conservation of energy
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
