solid |
resistance to changes of shape or volume |
|
liquid |
having a consistency like that of water or oil, i.e., flowing freely but of constant volume. |
|
gas |
an airlike fluid substance which expands freely to fill any space available, irrespective of its quantity. |
|
viscosity |
the state of being thick, sticky, and semifluid in consistency, due to internal friction. |
|
surface tension |
is the elastic tendency of a fluid surface which makes it acquire the leastsurface area possible |
|
freezing |
the freezing point of water. |
|
melting |
make or become liquefied by heat. |
|
evaporation |
is a type of vaporization of a liquid that occurs from the surface of a liquid into a gaseous phase that is not saturated with the evaporating substance. |
|
physical change |
a change that alters the form or apperence of a material but does not make the material into another substance |
|
chemical change |
a change in which one or more substances combine or break apart to form new substances |
|
condestation |
water that collects as droplets on a cold surface when humid air is in contact with it. |
|
Sublimation |
is the transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase. |
|
precipate |
cause (an event or situation, typically one that is bad or undesirable) to happen suddenly, unexpectedly, or prematurely. |
|
enothermic reaction |
(of a reaction or process) accompanied by or requiring the absorption of heat |
|
exothermic reaction |
is a chemicalreaction that releases energy by light or heat |
|
phase change |
. The states in which matter can exist: as a solid, liquid, or gas. When temperature changes, matter can undergo aphase change, shifting from one form to another.
