What is Matter?
Transcript of What is Matter?
V= Volume If you have a binder that has a mass of 2 grams and a volume of 240cm 3 Diving those you'd get a density of 0.00833g/cm 3 If you knew the density and volume then you'd need to figure out the mass. Do this by using the same formula D= m _ v A notebook has a volume of48cm and a density of 0.0625, what is the mass? By multiplying you'd find the mass to be 3. 3 ! 3 Physical Properties matter can be in the form of a gas, liquid or a solid. When it changes from one state to another, it's can be called melting, freezing, vaporization, evaporation, condensation, deposition, sublimation. Melting Melting is when a solid turns to a liquid when thermal energy is added. When the thermal energy is added, particles spread apart. ICe is a solid. When thermal energy is added, it turns to water which is liquid. Freezing Freezing is the opposite of melting. When thermal energy is taken away, a liquid can turn into a solid. If you get the same water and take away thermal energy, it will turn back into a solid, or ice. Vaporization vaporization is when a liquid turns into a gas, inside the liquid. The bubbles in the pot is a form of vaporization. The steam coming up is evaporation. Evaporation Evaporation is similar to vaporization, but the liquid changes to a gas at the surface of the liquid. Condensation Condensation is the change from a gas to a liquid On a cold bottle, the water on the plastic is a form of condensation. Sublimation Sublimation is when a solid turns into a gas without going into the liquid state. When you freeze carbon dioxide, you get dry ice; an example of deposition. When the solid turns back into a gas, it's sublimation Deposition Depostion is the a gas turning into a solid. Classes of Matter Matter is classified into mixtures, solutions, elements, and componds Mixtures A mixtures is when two or more substances are mixed together but not chemically combined. When they're mixed, the substances keep their own identities. Nothing new is created, but they can change their physical appearence There are two types of mixtures. Homogeneous and Heterogeneous Homogeneous mixtures look like it's the same thing throughout the mixture. Particles look like they're really small. Orange juice without pulp is a homogeneous mixture. Heterogeneous mixtures don't look the same throughout. It's least mixed, you can see the different substances, and it's fairly easy to separate. Solutions Solutions are a type of mixture where one substance is dissolved in another. All solutions are homogeneous mixtures. A solution is ALWAYS something dissolved in something else. To make a solution you have to have 3 things. A solute, a solvent, and solubility. Solubility is the ability for something to dissolve in a liquid. Solutes are what is being dissolved and solvent is what it's being dissolved in. In Iced tea, the tea is the solvent while the sugar/ sweetner is the solute. Metal solutions are alloys. An alloy is a solid dissolved in a solid. Bronze is an alloy of copper and tin. Elements An element is a pure substance made of atoms. Atoms is what all matter is made of. Atoms of the same element look the same. Different atoms means different atoms. The copper atom looks
than the zinc atom Compounds Compounds are made up of 2 or more elements that are chemically combined. They can be broken down into less complex things by heating them or using electrical energy. Compounds are made of molecules, which are made of 2 or more atoms. Water is hydrogen and oxygen. 2 atoms of hydrogen and 1 atom of oxygen. (H O) 2 vegetable soup is heterogeneous
