What is a gas?
A substance or matter in a state in which it will expand freely to fill the whole of a container, having no fixed shape (unlike a solid) and no fixed volume.
What is the first element?

What is the Kinetic Molecule theory?
Theory that says ALL particles/molecules are ALWAYS moving.
What tool is this?
Flask
What is the difference between Ionic and covalent bonds?
Ionic bonds transfer electrons, where as covalent bonds are formed by sharing.
What are 3 stages of the water cycle?

What equation are we using for this problem?
A sample of Freon gas has a volume of 2.23 liters, a pressure of 4.85 kPa, and a temperature of –1.36°C. Calculate the volume at a pressure of 1.38 kPa and a temperature of 5.5°C.
What is the tool called that we mix and test different chemicals with and looks like this?
Test tube
What is polar and nonpolar?
Polar molecules are when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms or when polar bonds in a larger molecule cancel each other out.
How many States of matter are there and what are they?
There are 4 and they are Solid, Liquid, Gas, and Plasma.
