A substance's density increases with its mass and decreases with its volume. So, a larger, heavier object will have more density than a smaller, lighter object.

Deposition is the phase change from gas to solid – dry ice turning into gas is sublimation.

Ductility is a material's ability to be stretched or drawn into a wire without breaking.

Adding heat to a liquid will usually cause it to evaporate or boil, not freeze. Freezing is the opposite process of heating.

Non-decaying matter includes substances that don't decompose naturally, like plastic or metal. Plants and dead organisms decompose over time.

All living organisms are affected by decaying matter, as it provides nutrients and plays a role in ecosystems.

Biodegradable materials break down naturally. Mixing them with non-degradable materials can hinder decomposition.

Product labels provide information about the product, including the manufacturing details to understand the product.
