Dylan Wang—8Br Ms. Cooney Chemistry 8 February 25‚ 2015 Chemistry Questions 1. Explain what is happening to the water molecules in the flat areas of the line on your graph during the phase changes from solid to liquid and liquid to gas. The water molecules are currently gathering potential energy to change from the differing states of matter. Due to thermal equilibrium‚ the water would need a set amount of energy to break through the changes in matter. This is why temperature slows down in these phase changes

2016‚ while in real terms (excluding inflation) sales will slip very slightly. Q: Which segments have most potential for growth? A: There is a clear divide between two promising segments – liquid soaps and shower gels – and two less buoyant ones – bar soaps and bath additives. Mintel expects liquid soap and shower gel

pumping storm water in civil and environmental. They are an integral part of engineering and an understanding of how they work is important. Pumps are devices that transfer mechanical energy from a prime mover into fluid energy to produce the flow of liquids. There are two broad classifications of pumps: positive displacement and dynamic. Dynamic Pumps Dynamic pumps add energy to the fluid by the action of rotating blade‚ which increases the velocity of the fluid. Figure 1 shows the construction

Have you ever seen dry ice‚ well let me show you. To measure the evaporation rate it is important to know that a half pound of dry ice will be placed outside and timed. The same thing will happen but in a cool room. If the dry ice is -109.3°F then it will evaporate in any condition warmer. The hypotheses is that the dry ice in the outside will evaporation faster. It is important to understand this because if you are trying to store dry ice and you put it in a freezer it will still evaporate. So in

When you were a little kid‚ glue was a fun tool. It held your Popsicle houses together and it was fun to peel off your hands after it dried. But glue is not just child ’s play; glue is a type of liquid that used cohesive and adhesive forces. These two forces work together to create tools that you can use in housework‚ at work at the office‚ and arts and crafts. Adhesion is the attachment of one material to another‚ due to a variety of potential interfaces. Adhesives are sticky substances that are

solid to a liquid or liquid to gas‚ the energy‚ it requires energy to do so. The potential energy stored in the interatomic forces between molecules needs to be overcome by the kinetic energy the motion of the particles before the substance can change phase. The energy required to change the phase of a substance is known as a latent heat. The word latent means hidden. When the phase change is from solid to liquid we must use the latent heat of fusion‚ and when the phase change is from liquid to a gas

learn filtering techniques. Specifically‚ to form and filter a calcium carbonate precipitate using a Buchner funnel. Procedure: a.) Prepared a mixture of .5 M calcium nitrate (45 mL) and .01 M sodium carbonate by combining and stirring the two liquids in a beaker. Allow the mixture to stand. b.) Prepare the filtration assembly. The assembly consists of a tapered flask with a buchner funnel inserted in the top. The funnel has a rubber stopper attached to its stem in order to properly fit into the
