Changes of state

What are the three states of matter?

Solids, liquids, and gases

Match the state of matter with its particle arrangement:

Solid ↔ Tightly packed, regular pattern

Liquid ↔ Close, can move past each other

Gas ↔ Widely spaced, move randomly

Effects of temperature and pressure on the state of matter

1⃣ Increasing temperature leads to melting or vaporization

2⃣ Decreasing temperature leads to freezing or condensation

3⃣ Increasing pressure leads to condensation or solidification

Why do liquids take the shape of their container?

Particles can move past each other

What happens to energy during the latent heat of fusion?

Absorbs or releases

What is specific latent heat defined as?

Energy to change state

Steps involved in calculating the energy required for latent heat of fusion

1⃣ Determine the mass of the substance

2⃣ Identify the specific latent heat of fusion

3⃣ Use the formula E=E=mLfmLf​

4⃣ Calculate the energy required
