|
The state of matter in which particles are arranged in either crystalline or amorphous form |
solid |
|
|
This type of solids are not arranged in a regular pattern |
amorphous |
|
|
According to Boyle's law, when the pressure of a gas increases at a constant temperature, its volume does this. |
Decreases |
|
|
When snow on the ground decreases even if the temperature stays below zero degrees Celsius. The process from a solid to a gas. |
Sublimation |
|
|
The change from a liquid to a solid |
Freezing |
|
|
The surface of water can act like a sort of skin due to a property of liquids called |
surface tension |
|
|
The state of matter in which changes volume most easily is |
gas |
|
|
When boiling a pot of water and there are water droplets on the lid of the pot. What has happened before the condensation has occurred? |
vaporization |
|
|
The greater the speed of gas particles in a container the |
greater the pressure |
|
|
An example of a liquid with high viscosity is |
corn syrup |
|
|
When a substance cools, what happens to its thermal energy? |
It is lost to its surroundings. |
|
|
The motion of particles in a gas |
are constantly moving. They are independent and spread apart as they fill the container. |
|
|
The motion of particles in a liquid |
are freely moving. They slide around one another and flow, but are still touching one another. |
|
|
The motion of particles in a solid |
are in a fixed position. They are closely locked into position and move back and forth slightly. |
|
|
The water molecules in a puddle |
absorb thermal energy. They go from a liquid state to a gas state as they evaporate. |
|
|
A helium balloon on a cold day |
will shrink because the molecules lose thermal energy. |
|
|
As an ice cube melts |
it gains thermal energy and changes state from a solid to a liquid. |
