The 4 States of Matter You’ve probably heard of solids, liquids, and gases, but the most common state (aka phase) of matter in the Universe is something else. Hint: it’s what stars are made of

Solids Solids have a definite shape and volume. Example: metal cube

Liquids Liquids have a definite volume, but their shape changes to fill a container. Example: water

Gases Gases don’t have a definite shape or volume: they fill whatever container they’re in Example: chlorine

Plasma Plasma is the 4 th state of matter. It is a superheated gas, and behaves like a gas. It’s so hot atoms begin losing electrons! Example: the Sun

Energy The state a substance is in depends on its temperature Temperature State

Changes of State The melting/freezing point of a substance is the temperature at which it begins to change from a solid to a liquid or vice versa. The boiling point of a substance is the temperature at which a liquid begins turning into a gas

Types of compounds CHANGE GEARS – NEW TOPIC Compounds are classified as organic or inorganic depending on what elements they contain

Inorganic Compounds An inorganic compound is one that doesn’t have any carbon-carbon bonds. Water

Organic Compounds An organic compound is one that contains at least 1 carbon-carbon bond. Generally, anything with more than 1 carbon atom is considered organic. Sugar Ethanol Amino Acid
