Front

What are the three main states of matter?

Back

Solid, Liquid, Gas.

Front

What is the defining characteristic of a solid?

Back

Particles are closely packed together and vibrate in place.

Front

How do particles in a liquid behave compared to those in a solid?

Back

Particles in a liquid are close together but can move past one another, allowing liquids to flow.

Front

What happens to the particles of a solid when heat is added?

Back

The particles gain energy and move faster.

Front

What is the process called when a gas turns into a liquid?

Back

Condensation.

Front

What is the effect of temperature on the state of matter?

Back

Increasing temperature can cause solids to melt into liquids and liquids to evaporate into gases.

Front

What is the term for a mixture where one substance is dissolved in another?

Back

Solution.

Front

How does pressure affect the state of matter?

Back

Increasing pressure can force gas particles closer together, potentially turning them into a liquid.

Front

What is the concentration of a solution?

Back

The amount of solute (e.g., citric acid) present in a given volume of solvent (e.g., water).

Front

If a solution has 400 g of solute in 2000 mL of solvent, what is the concentration?

Back

0.2 g/mL.
