    • 4 Pages

    The Floating Egg Problem Introduction: This experiment was constructed to aid in the practice of using the volumetric system and the glassware that determines volume. Volumetric glassware contains an accurate amount of liquid and also measures the volume accurately. Density is a measure of how much matter takes up a certain amount of space or volume. The more matter you can pack into a certain space‚ the denser it is. Although we often confused the two‚ density and weight are actually two

    Sugar‚ or Pepper)? Background Information Water can be found as a liquid‚ solid‚ or gas. Water is made up of tiny particles which are hard to see in solids. A solid is matter that has a shape and usually takes up space. Its particles are closely packed together. The particles have some energy. They move back and forth‚ but they do not change places with each other. These tiny particles move around when water is in its liquid form‚ but as the temperature gets colder; they slow down and move less

    Catie Bates 10/22/2014 Physical Science Physical Changes I like physical changes more than chemical changes. Some reasons are‚ physical change is "easily" reversible‚ how liquids can become solid and vice versa‚ the solid disappears but just the application of heat can boil the water off and get the salt back in the same form. Therefore‚ I like physical changes more than chemical changes. I like physical changes more than chemical changes because physical change is "easily" reversible because

    of diameter d = 3500mm and 5km long is used to pump water. An obstruction plugs the pipe at an unknown location so that no liquid can flow. A piston is placed in one end of the pipe and slides (without leakage)‚ compressing the water in the pipe. The pressure increases 855 k Pa when the piston is moved a distance of 734mm into the pipe. If the temperature of the liquid =300 C‚ how far down the pipe would you estimate the obstruction to be? 3- Derive an expression for the capillary height change

    non-diffusing air that was passed over the test tube at the temperature of 50oC.Thetemperature is kept constant and air stream is passed over the top of the tube to ensure that the partial pressure of the vapor is transferred from the surface of the liquid to be air stream bymolecular diffusion. The initial reading and every 2 minutes subsequent reading of the liquidacetone level are determined‚ and the experiment is conducted for 10 minutes. The experiment is repeated by changing temperature to 45oC

It is important to make certain that there is no air bubble in the tip of the buret below the stopcock before the initial reading of the liquid level in the buret is taken. If a 0.5-mL air bubble is present in the tip of a buret‚ what percent error in 10-mL‚ 20-mL‚ and 40-mL samples will result if the air bubble is dislodged
