Question
Answer
Compressed   forced or closed together  
🗑
Kinetic Theory of Matter   a theory that matter is made of atoms and molecules which act like tiny particles that are always in motion  
🗑
Evaporation   the change of state from a liquid to a gas  
🗑
Condensation   the change of state from a gas to a liquid  
🗑
Boiling   the temperature at which a liquid boils  
🗑
Vaporization   change of a liquid or solid substance to a gas  
🗑
Solidification   change from a liquid or gaseous to a solid form  
🗑
Sublimation   the process in which a solid changes directly into a gas.  
🗑
Deposition   the process of changing of a gas to a solid without passing through an intermediate liquid phase  
🗑
Melting   the temperature at which a solid changes into a liquid  
🗑
Law of Conservation of Mass   mass cannot be created or destroyed  
🗑
Law of Conservation of Energy   energy cannot be created or destroyed  
🗑
Pressure   the amount of force exerted per unit area of a surface  
🗑
Pascal   the SI unit of pressure; equal to the force of 1N of an exerted over an area of 1M squared.  
🗑
Buoyant Force   the upward force that keeps on a object immersed in or floating on a fluid  
🗑
Viscosity   the resistance of a gas or liquid to flow  
🗑
Archimedes' Principle   the buoyant force on an object in a fluid is an upward force equal to the weight of the fluid that the object displaces  
🗑
Pascal's Principle   a change in pressure at any point in an enclosed fluid will be transmitted equally to all parts of the fluid  
🗑
Hydraulic Device   a device that uses pressure from one point to another  
🗑
Bernoulli's Principle   as the speed of a moving fluid increases, the pressure of the moving fluids decreases  
🗑
Gas Laws   the laws that state the mathematical relationships between the volume,temperature,pressure, and quantity, of a gas  
🗑
Charles' Law   for a fixed amount of gas at a constant pressure, the volume of the gas increases as the gas's temperature increases. Likewise the volume of the gas decreases as the gas's temperature decreases  
🗑
Boyle's Law   for a fixed amount of a gas at a constant temperature,the volume of a gas increases as the gas's pressure decreases. Likewise, the volume of a gas decreases as the gas's pressure increases  
🗑
Gay-Lussac's Law   the pressure of a gas increases as the temperature increases, if the volume of the gas does not change. The pressure decreases if the temperature decreases  
🗑
Freezing   the temperature at which a liquid changes into a solid  
🗑


   

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.
