Part B: Fill in the Blank
Write the correct answer on each line.
1. A material that flows and takes the shape of its cup is a liquid.
Liquids change shape to match their container but keep the same amount.
2. A material that holds its shape on the table is a solid.
Solids keep a fixed shape, so they sit on the table without spreading out.
3. A material that is often invisible and fills the whole room is a gas.
Gases spread out and fill every corner, often without being seen.
4. When we heat ice enough, it melts into water.
Melting is the name for the change from a solid into a liquid.
5. Ice, water, and steam are all the same stuff — just different states.
All three are water in different states, shown by different looks and feels.
