Solid, Liquid or Gas Matching Worksheet (teacher made) - Free Printable

Problem Description:

The task involves categorizing different substances as solid, liquid, or gas based on their physical states. The provided images and words need to be matched with the correct category.

Solution:

#### Step 1: Understand the Categories
- Solid: A substance with a definite shape and volume. Examples include chocolate, foil.
- Liquid: A substance that has a definite volume but takes the shape of its container. Examples include juice.
- Gas: A substance that has neither a definite shape nor a definite volume. It expands to fill its container. Examples include steam, helium, and coffee (when it's in vapor form).

#### Step 2: Analyze Each Substance
1. Chocolate: Chocolate is a solid because it has a definite shape and volume. It does not flow like a liquid or expand like a gas.
- Category: Solid

2. Steam: Steam is water in its gaseous state. It has no definite shape or volume and expands to fill its container.
- Category: Gas

3. Foil: Foil (usually made of metal) is a solid because it has a definite shape and volume. It can be bent or shaped but does not flow like a liquid or expand like a gas.
- Category: Solid

4. Juice: Juice is a liquid because it has a definite volume but takes the shape of its container. It flows freely.
- Category: Liquid

5. Helium: Helium is a gas because it has no definite shape or volume and expands to fill its container.
- Category: Gas

6. Coffee: Coffee, when in its liquid form, is a liquid because it has a definite volume but takes the shape of its container. However, if it is being discussed in terms of vapor (e.g., steam from boiling coffee), it would be a gas.
- Category: Liquid (assuming it is in its liquid form)

#### Step 3: Match the Substances to Their Categories
Based on the analysis:
- Solid: Chocolate, foil
- Liquid: Juice, coffee
- Gas: Steam, helium

#### Final Answer:
\[
\boxed{
\begin{array}{ll}
\text{Chocolate} & \text{Solid} \\
\text{Steam} & \text{Gas} \\
\text{Foil} & \text{Solid} \\
\text{Juice} & \text{Liquid} \\
\text{Helium} & \text{Gas} \\
\text{Coffee} & \text{Liquid} \\
\end{array}
}
\]

This categorization ensures that each substance is correctly identified based on its physical state.
