No, there is no particles nor pressure in a vacuum.
Can there be gas in a vacuum?
200
A substance cools and the particles slow down and move slower.
When kinetic energy decreases, what happens to the substance and particles?
200
The empty space with no particles or pressure.
What is a vacuum?
200
When liquids turn into gas.
What is the process of vaporization?
200
An element with two or more different forms of an element in the same physical form.
What are allotrops?
300
Particles in a _______ attracted to each other. These attractions keep the particles close together causing them to have a definite volume.
