What is the most common state of matter in the universe?
Plasma
Does liquid move to the shape of its container?
Yes.
Ice is the solid form of what substance?
Water
What do gases do to the space or container they are in?
They fill it completely
What state of matter makes up the Sun and stars?
Plasma
This process changes a liquid into a gas.
Evaporation
What do particles in a solid do when they are tightly packed together?
Vibrate.
What process changes a liquid into a gas at the surface of the liquid?
Evaporation
What two charged particles make up plasma?
Ions and electrons
Liquid particles slide past each other, allowing liquids to do this easily.
Flow
What process changes a solid directly into a gas without becoming a liquid?
sublimation.
How are gas particles spaced compared to solid and liquid particles?
They are very far apart
Why does plasma conduct electricity so well?
Because it contains freely moving charged particles
This property of liquids describes how easily they flow, such as water flowing faster than honey.
viscosity
Why do solids keep their shape instead of flowing like liquids?
Their particles are tightly packed and only vibrate in place
Why can gases be easily compressed compared to solids and liquids?
Their particles are far apart with lots of empty space between them
What natural event on Earth is an example of plasma?
Lightning
