Matter can change from one state to another when energy (usually heat) is added or removed: - Melting: Solid to liquid (e.g., ice melting into water) - Freezing: Liquid to solid (e.g., water freezing into ice) - Evaporation: Liquid to gas (e.g., water turning into steam) - Condensation: Gas to liquid (e.g., steam turning back into water droplets) - Sublimation: Solid directly to gas (e.g., dry ice turning into carbon dioxide gas) C. (COPY AND ANSWER) ACTIVITY NOTEBOOK Directions: 1. Look around your house and find 2 examples of each state of matter: solid, liquid, and gas. 2. List them in the correct column in the table below. 3. Write what you observed that helped you decide the state of matter for each item. | State of Matter | Example from Home | What I Observed | | :-------------- | :---------------- | :------------- | | Solid | 1. | | | | 2. | | | Liquid | 1. | | | | 2. | | | Gas | 1. | | | | 2. | |
Answer (1)
Let's explore examples of different states of matter you can find at home. Each state of matter has distinct characteristics.
Solid :
Table - Observations: A table is rigid and maintains a definite shape and volume, which is characteristic of solids.
Book - Observations: A book is firm and retains its shape, another example of a solid.
Liquid :
Water - Observations: Water takes the shape of its container and flows, which are properties of liquids.
Juice - Observations: Juice, like water, conforms to the shape of its container and has a definite volume.
Gas :
Air - Observations: Air is invisible but can be felt (e.g., when you blow on your hand). It fills any container it's in.
Steam - Observations: Steam is vapor you can see when boiling water, and it dissipates in the atmosphere, which are characteristics of gases.
Each example illustrates the unique properties of solids, liquids, and gases found in everyday life.
