Unit 2 Learning Set Flashcard 1

Front

What is the mass of air?

Back

Air has mass, which can be demonstrated by measuring the mass of an inflated ball compared to a deflated one.

Front

How does an odor escape a container?

Back

An odor escapes a container by moving into the air in the room from the container.

Front

How can you determine which container is full of gas, half-full, or empty?

Back

By measuring the mass of each container: the one with the most mass is full, the one with the least mass is empty, and the one in the middle is half-full.

Front

What space does air occupy?

Back

Air occupies space in the room, meaning it takes up volume.

Front

Can menthol exist in different forms?

Back

Yes, menthol can exist as a solid, liquid, and gas. It can change from solid to liquid when heated and can also evaporate into gas.

Mass is a measure of the amount of matter in an object, typically measured in grams or kilograms.

Front

What is the principle of buoyancy?

Back

Buoyancy is the ability of an object to float in a fluid, which is determined by the object's density compared to the fluid's density.

Front

What is the difference between a solid, liquid, and gas?

Back

Solids have a definite shape and volume, liquids have a definite volume but take the shape of their container, and gases have neither a definite shape nor volume.

Front

What is the process of evaporation?

Back

Evaporation is the process by which liquid turns into gas, usually when heated.

What is the definition of density?

Back

Density is the mass of an object divided by its volume, often expressed in grams per cubic centimeter (g/cm³).
