|---|---|---|---|---|---|
| solid | matter that has a definite shape and a definite volume. definite crystalline arrangement.
🗑
|
||||
| vapor | a gaseous state of a substance that is normally a liquid at room temperature
🗑
|
||||
| vaporization | at constant temperature, it is a process in which particles in the liquid phase gain enough energy to break away into the gaseous phase. also known as boiling
reverse of condensation
🗑
|
||||
| sublimation | the process in which a solid changes directly into a gas;
a phase skipper
reverse of deposition
🗑
|
||||
| liquid | a phase of matter having a definite volume but not definate shape...takes the shape of its container
( a shape shifter)
🗑
|
||||
| HEAT OF FUSION | amount of heat needed to convert a unit mass of a substance from a solid to its liquid at its melting point.
🗑
|
||||
| HEAT OF VAPORIZATION | THE AMOUNT OF HEAT NEEDED TO CONVERT A UNIT MASS OF A SUBSTANCE FROM A LIQUID TO A VAPOR AT ITS BOILING POINT
🗑
|
||||
| exothermic | a chemical reaction that releases heat, producing products with less potential energy then the reatants
🗑
|
||||
| freezing point | the constant temperature process in which both the solid and liquid phase existt in equilibrium, the same temperature as the substance's melting point
🗑
|
||||
| endothermic | a chemical reaction that absorbs heat, producing products with more potential energy then the reactants
🗑
|
||||
| deposition | the process in which a gas changes directly into a solid. the reverse of sublimation
🗑
|
||||
| condensation | an exothermic process which a vapor or gas changes into the liquid phase, the potential energy of a substance decreases during this constant temperature process
the reverse of vaporization
🗑
|
||||
| boiling point | the temperature at which the vapor pressure of a liquid is equal
to the atmospheric pressure
🗑
|
||||
| specific heat capacity | the heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree).
🗑
|
||||
| gas | an airl ike fluid substance which expands freely to fill any space available, irrespective of its quantity.
🗑
|
||||
| Force of attraction | a force that draws an object close due to its attraction.
same as inter-molecular force (IMF)
🗑
|
||||
| Kinetic energy | energy that a body possesses by virtue of being in motion.
🗑
|
||||
| Potential energy | the energy possessed by a body by virtue of its position relative to others, energy at rest
🗑
|
||||
| solid | regular repeating geometric pattern
🗑
|
||||
| IMF | inter molecular forces
🗑
|
||||
| force | attraction between molecules
🗑
|
||||
| bond | is between atoms
🗑
|
||||
| calorimetry | the science of measuring the change in heat that comes from a chemical reaction
🗑
|
||||
| enthalpy | a thermodynamic quantity equivalent to the total heat content of a system
🗑
