FAQ’S

Q: What is density?

A. Density is a combination of mass and volume. Mass is how much matter is in an object and volume is how matter takes up space. Density is also to determine whether an object or item will float or sink to the bottom of the water. For example, a piece of wood that has holes can float and a rock will sink to the bottom. Why will that happen? The piece of wood had weak density and the rock had a strong density.

Q. What are the physical properties of matter?

A. Some of the physical properties of matter are: volume, mass, and weight. Weight is how much gravity pulls on the object, mass, or mass. Weight is also measured with a scale, but if there is no gravity on the scale, it won’t work one bit. Mass is how much matter is in an object or item. In addition to mass, it is really well measured in grams. Last but not least, volume. Volume is how much matter takes up space. Furthermore, to measure the right amount of volume in water, you may use a graduated cylinder. As you can see, mass and volume is a combination of density. There are 5 ways to identify these physical properties of matter. They are: hearing, smell, sight, touch, and taste.

Q. What is matter?

A. Matter is everywhere! Matter is anything around you! Matter can even be right in front of you. Matter can either be a solid, liquid, or gas. Never the less, matter all has mass, weight, and volume. Matter is also made of atoms. Atoms are made up of protons, neutrons, and electrons. In addition, atoms are the smallest property of elements and it millions of them come together to make matter. Matter is anything that takes up space and has mass. FACT: You are matter.

Q. What are the 5 states of matter?

A. Solids are the first state of matter. It has a definite shape and has little space to move around. The 1st state of matter also collides with near neighbors, has a lined pattern, and has strong bonds. Solids can be made a changed by freezing and melting. One way of changing a solid is by melting it. The melting point of water is anything above 32℉. For example, an ice cube will melt above any temperature that is 32℉ will melt into a liquid.The second way to change or make a sold is by freezing. The freezing point is about 32℉. Another example is when a glass of water get to the freezer to about the temperature of 32℉ and the glass starts to burst and crack because the solid takes up more space, but has the same amount of mass. Another way is sublimation. Sublimation is when a solid turns into a gas without going into the liquid state. One example of sublimation is when on object like dry ice can turn from a solid to a gas without going into the liquid state.

Liquids are the second state of matter. They are different to solids, but also has a definite shape just like solids. Liquids have weak bonds, takes the shape of its container, and moves freely in its volume. Another fact about liquids is that when it has no container to take up its volume, it spreads as far as it can. To physically change a liquid is by freezing, boiling, and evaporation. To physically make a liquid is by melting. Making a liquid freezes at the temperature at 32℉ will change a liquid into a solid. Another way to change a liquid physically is by boiling. With the right amount of heat around 212℉ will start to boil and the steam is as in the air. The 3rd way to change a liquid is by evaporation. Evaporation is another way to change a liquid into the gas state. When water is on the ground outside, the heat from the sun makes the liquid warm up. Creating the liquid into a gas. One way to make a liquid physically is by melting ice at the temperature at 32℉.

Gases are the third state of matter. They have lots of space to move around in its volume, and moves faster than a liquid.

Q. What are the changing states of matter?

A. The changing states of matter are: melting, freezing, boiling, evaporation, sublimation, and condensation. Melting is when a solid turns into liquid at the temperature above 32°F the liquid will start to melt. Freezing is at the temperature anything at the temperature 32ºF the liquid will freeze and will turn into a solid. Another common changing state is boiling. Boiling water can be up to 212ºF and will start to start to make little bubbles creating steam . The steam is gas which was from liquid to gas. In addition, there us evaporation. Evaporation happens when the water on the floor gets heated up by the sun. The liquid gets turned into steam (which is gas), but cannot be seen easily.  Sublimation is when a gas is formed by a solid. For example, dry ice is heated at the right temperature and will be changed to dry ice. Condensation is different. A gas can be formed into a liquid with the changing state condensation. For example, rice that is covered with glass on the top can get heated by the steam. The steam is a gas that can escape. So, the gas (steam hits the glass and turns back into a liquid.

Q.  What ISN’T matter?

A shadow is not matter. It can be seen, but it has no mass. It does not take up space. Other things aren’t matter are heat, light, energy, and sound. These things aren’t matter because they don’t have mass. Mass is how much matter is an object.
