    solubility. 2. What are the three properties of matter? The three properties of matter are gas‚ solid‚ and liquid. 3. What is matter made up of? Matter is made up of tiny particles. 4. Compare and contrast the movement of particles in solids‚ liquids‚ and gases. Solids: They move back and forth. They do not change places with each other‚ and they have a definite shape. Liquids: Changes shape‚ does not have a definite shape‚ takes up a definite amount of space‚ and will take up the

    Anise oil was successfully able to be extracted from anise seeds during this experiment. It was done by first crushing the seeds‚ then placing them into a distillation apparatus. The distillation apparatus evaporated the liquid from the seeds‚ which was captured in a flask. Next‚ DCM was added to the distillate‚ which allowed the water to be separated from the anise oil. Finally‚ the DCM evaporated and the pure anise oil was collected. The process of steam distillation allowed the anise oil in

    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

    appliances and is used in commercial kitchens. Fires involving cooking fats and oils (classified as class K (US) or F (Australia/Europe/Asia)) burn hotter than flammable liquids‚ rendering a standard class B extinguisher ineffective. Flammable liquids have flashpoints under 100 degrees Fahrenheit. Cooking oil is a combustible liquid since it has a flashpoint over 100 degrees. Such fires should be extinguished with a wet chemical extinguisher. Extinguishers of this type are designed to extinguish cooking

    MEA solvents approved the higher reactivity of PZ solvent. According to the thermal energy requirement for solvent regeneration‚ PZ process consumed less energy than the MEA process and this result demonstrated another advantage of PZ over MEA. The liquid absorbent in PZ process has higher cyclic loading than in MEA process which will lead to a lower heat requirement in PZ process. Moreover‚ PZ process has high absorbent loadings that resulting in high performance of the regeneration process of PZ

    (g/mL) for liquid samples of matter. For that reason if the volume is known of a liquid‚ determining its density is easily determined by weighing it accurately. Density can also be used as a tool for finding the concentration of solutions in some cases. The density is different in a substance when a substance is added to a pure liquid to when both the solute and solvent were separate all together. There are many ways to determine density. This method determined the density of a liquid by weighing

    teaching chemical density‚ people often allude to a substance’s tendency to sink or float. This is technically incorrect. A much better analogy is whether a substance mixes with another substance or not. In the case of the lava lamps three different liquids are used – water‚ vegetable oil and food coloring. Oil is less dense than water so it does not mix with the water. Food coloring is denser than water‚ so it drops through the oil and settles in the water mixing with it. The chemical reaction is a
