gas
A substance fills a 1-liter bottle. A scientist transfers the substance to a 2-liter bottle. The substance increases in volume and fills the new space. What is the state of matter of this substance?
A liquid has a definite volume but does not have a definite shape.

Gases do not have a definite shape, liquids take the shape of their container, and solids have a definite shape.
How can you differentiate solids, liquids, and gases based on this picture?
A substance with a definite shape and volume is changing to a substance with a definite volume but not a definite shape.
Imagine a picture of a Melting snowman - how do you know there are two different states of matter in the picture?
They all have a definite shape.
Jacks' garden is full of small flowers and his front yard is a sun flower. What is one reason why the small flowers and the Sun flower are all identified as a solid?

Julie sees a plastic Publix bag blowing down the beach. How does Julie know that moving air is considered a gas?

A solid has a definite shape.
What does this picture prove about Solids?
solid
a substance that has a definite shape and volume
liquid
a substance that has a definite volume but no definite shape
gas
a substance without a definite volume or shape
true
