Back

The particles compress.

Front

What can be said about air particles in a closed syringe system?

Back

No more air particles can be added or taken away.

Front

How are particles outside a soccer ball arranged compared to those inside?

Back

Elements are made of particles.

Front

What is the definition of a particle?

Back

A particle is a small localized object to which can be ascribed physical properties.

Front

What is the relationship between pressure and volume in a gas?

Back

As pressure increases, volume decreases (Boyle's Law).

Front

What happens to gas particles when they are heated?

Back

They gain energy and move faster, causing expansion.

Front

What is the principle of conservation of mass in chemical reactions?

Back

Mass is neither created nor destroyed in a chemical reaction.

Front

What is the difference between a solid, liquid, and gas in terms of particle arrangement?

Back

Solids have closely packed particles, liquids have loosely packed particles, and gases have widely spaced particles.
