Matter and Its States Created by misterrohman

Matter and Its States What kind of state can you see in this picture? All matters fill the space, have mass, and can be in the form of different states. Basically, there are three states of matter: solid, liquid, and gas. The state of certain matter depends on its temperature. For example, water becomes ice (solid) in the low temperature and water (liquid) in the room temperature. At the higher temperature, water changes into vapour (gas). Every state of matter has specific properties that can be used to identify the matter itself.

3.1 To investigate the property of matter based on its state and application in daily life. Basic Competence Menyelidiki sifat-sifat zat berdasarkan wujudnya dan penerapannya dalam kehidupan sehari-hari

In this activity you will investigate properties of matter either in solid, liquid or gas. Apparatus and Materials a wooden block a cup a cup of water a glass a balloon a measuring cylinder a ruler a board marker

Procedures 1. Use the measuring cylinder to measure 50 mL of water. Pour the 50 mL of water into a glass. What is the shape of the water after you pour it into the glass? By using a small board marker, write a mark on the glass where the water surface is shown. measuring cylinder What is the shape of the water after you pour it into the glass?

Now pour the water into a cup. What is the shape of the water after you pour it into the cup? By using a small board marker, write a mark on the part where the water surface is shown. Then, measure the volume of the water. Does the volume of the water change? Does the volume of the water change?

Look at the wooden block. What is the shape of the block? Measure its length, width, and height. Put the block in an empty glass. Does the shape of the block change? Write down the result of your observation and measurement of the block. Solid Every solid has unchanged shape and volume. For example, the shape of your pencil is still a pencil although it is put in your hand or in a glass. A pencil has an unchanged volume since pressure cannot compress the pencil into smaller space. What causes solid to have fixed shape and volume? Matter consists of tiny particls that continually move. This theory is later known as the kinetic theory of matter. Does the shape of the block change?

Blow air into the balloon to inflate it and tie it so that the balloon is not deflated. What is the shape of the air in the balloon? Then, push the balloon slowly. Can you change the shape of the air? Can you change the shape of the air?

conclusion Solid. Every solid has unchanged shape and volume . Liquid. Liquid flows and its shape are similar with the shape of its container and fixed volume. Shape of liquid depends on the shape of its container. Gas. Gas has no fixed shape and volume. Zat padat mempunyai bentuk dan volume tidak berubah. Zat cair mengikuti bentuknya sama dengan bentuk tempatnya. Bentuk zat cair bergantung pada bentuk wadahnya. Gas mempunyai bentuk dan volume tidak tetap.

Analysis 1. What is the state of these matters? a. water b. wooden block c. air 2. Think about the wooden block. Do its volume and shape change? 3. Do all solids have fixed volume and shape? 4. Think about the activity that you have just done. Write down the properties of solid, liquid, and gas.

Questions 1. What is the shape of the air when it is filled into a volley ball and a soccer ball? 2. Can you fill a balloon with a wooden block? Why? What about water, can you fill a balloon with water? 3. Write down five kinds of objects. Are they solid, liquid or gas? Compare your work with your friends' work.
