    We recently did an experiment on osmosis and it really helped me understand diffusion and osmosis much better. This experiment was really easy. We put the egg into three different types of liquids, vinegar, corn syrup, and water. My hypotheses for the egg in the vinegar was that the shell would be removed and dissolve. For the corn syrup I thought that the whole egg would break apart including the including the yolk. My hypothesis for the water was that nothing will happen to the egg. 1. Get egg...

    ... dates. An example of the most well known and studied fault is the San Andreas Fault located of the coast of California. The origin of volcanoes: Hot spots, can be found on plate boundaries or inside the plates. The hot spot is a place deep inside the Earth that begins to form molten lava from extreme heat conditions. It will quickly rise up, pushing and melting its way to the surface resulting in a volcano. Because of the constant moving of the plates, the volcano will be carried away from t...

    Chemistry Independent Study: Gas Laws Since the days of Aristotle, all substances have been classified into one of three physical states. A substance having a fixed volume and shape is a solid. A substance, which has a fixed volume but not a fixed shape, is a liquid; liquids assume the shape of their container but do not necessarily fill it. A substance having neither a fixed shape nor a fixed volume is a gas; gases assume both the shape and the volume of their container. The structures of gases...

  • 2 H 2 O Carbon Monoxide
    1,607 words
    1. State the five assumptions of the Kinetic-Molecular Theory of gases. a) Gases consist of large numbers of tiny particles. These particles, usually molecules or atoms, typically occupy a volume about 1000 times larger than occupied by the same number of particles in the liquid or solid state. Thus molecules of gases are much further apart than those of liquids or solids. Most of the volume occupied by a gas is empty space. This accounts for the lower density of gases compared to liquids and so...

  • Concentration And Reaction Rate

    ter> How concentration affects reaction rate. The aim of this investigation is to see how the concentration of a reactant in ratio to the reactor affects the rate of a reaction. When hydrochloric acid and Thiosulphate react together sulphur is liberated this means that as the reaction goes on the solution will become yellow and will change from being transparent to translucent to opaque. The sulphur is formed as a solid but not in the usual precipitation way. Na 2 + S 2 + 2 HCL 2 NaCl+...

    The first thing water reminds us of is the clear liquid in our water bottles. However, water is more than a normal substance. Water is the beginning and the continual of life on earth. Because of its many unique properties, water was able to start life on our planet. The simple structure of H 2 O is the source of all water's properties. With two hydrogen atoms sticking to an oxygen atom in a tetrahedron shape, water is considered as a polar molecule. Because oxygen is very electronegative, it pu...

  • Three Phases Law States
    528 words
    Solids, liquids, and gases are the three main, or fundamental phases of matter. Each one has a different density and a different level of stability. What determines the stability of each phase is the bond between its atoms. The tighter the bond between its atoms the more stable that phase of matter is. Solids are the most stable form of matter, followed by liquids, and then gases. Solids have a definite shape and do not take the shape of their container. Liquids do not have any definite shape an...

    Before we look at insulation we must see how thermal energy moves. There are three ways it moves. The first is by conduction. Conduction is the transfer of energy by direct contact of particles. Heat spreads through out an object till the object is the same all the way around. (Physical Science section 6. 1, page 1) This happens because all particles vibrate unless in an absolute zero situation. These more violently moving particles hit each other. Eventually these particles will vibrate at the ...

  • Positively Charged Positive Charge
    1,691 words
    Lightning is a discharge of static electricity in the atmosphere, which causes a bright flash of light. When lighting goes through the air, it heats the air to degrees hotter than the suns surface about 50, 000 degrees fahrenheit. This heating causes the air to expand and contract. This causes the sound called thunder. Lightning is caused by a build up of negative ions in the atmosphere which discharges into the ground causing the negative ions to go with the positive ions in the ground. Static ...
