SISTEMA Definición: Porción del universo, objeto de nuestro estudio. Puede estar formado por uno o varios cuerpos los cuales pueden interactuar entre sí. Clasificaciones 1) Abierto: sin límites físicos. Intercambia materia y energía con el medio Cerrado: con límites físicos. Intercambia energía pero no materia con el medio. Aislado: con límites físicos. No intercambia ni energía ni materia con el medio. 2) Homogéneo: tiene solo una fase y todas sus

morning). Result The salted ice quickly makes the sides of the glass jar very cold. As the water that exists in the air as a gas hits the cold sides of the jar, it changes into a liquid! This process is known as condensation, which is the opposite of evaporation. There is water in the air at all times, but we don't see it since it's in a gaseous state. Our experiment turns the gas into a liquid, allowing us to physically see the

Impurities are substances inside a confined amount of liquid, gas, or solid, which differ from the chemical composition of the material or compound.Impurities are either naturally occurring or added during synthesis of a chemical or commercial product. During production, impurities may be purposely, accidentally, inevitably, or incidentally added into the substance An interfering agent is a thing added to a sugar syrup to prevent crystallization. Coat is naturally the skin of humans and animals

how much aquatic life can be supported within an environment (Metro 1990). Along with having the correct amount to Hydrogen ions, both the stream and the wetland have a level on dissolved oxygen level. This level is measured to the amount of oxygen gas bubbles within the water that the aquatic life uses to sustain itself. This oxygen is also used to decompose of organic matter (Metro 1990). The purpose of this experiment is to test to determine to what levels of both pH and dissolved oxygen are processed

of water. * Temperature (100°C): It is important to acknowledge that the temperature at which water boils is 100°C. This is controlled by how much gas and fire is released from the Bunts & Burner. * Time (seconds): The time is highly important. Time is controlled by how much gas is released from the Bunts & Burner. The lower the gas, the longer it will take for the water to boil due to low heat. SCOPE AND LIMIT The range of your measurements (from x to y) and the size of the increments

part of the industry, the URCP phenomenon is becoming a more and more common problem in the industry. Over the course of a couple of decade the following issues have been documented. * In October 1985, an incident related to URCP occurred in a PE gas system which was reported in Szeged (Hungary) over a length of 700 m. Other long running cracks were also observed on the tubes & pipesline system. The crack was initialed at the time of installation. * In 1989, an incident occurred in Antwerp

of heating and cooling. Water enters at the end of the tube. The thermometer is placed inside the distilling flask. Anti-bumping granules are used to provide many places where bubbles of gas may form as the water boils. The bubbles are small and rise steadily to the surface of the liquid where they burst. Without the granules, fewer but larger bubbles form. They rise and burst with such force that they shake the test tubes which can be

what occurs when heat is added or removed from a substance and how to calculate the enthalpy change. Answer In a gas, the potential energy (energy of attraction) is small to the kinetic energy thus, on average, the particles are far apart. This large distance has several macroscopic consequences : a gas fills its container, is highly compressible, and flows easily through another gas. In a liquid , attractions are stronger because the particles are touching, but they have enough kinetic energy to

Solubility is the property of a solid, liquid, or gaseous chemical substance called solute to dissolve in a solid, liquid, or gaseous solvent to form a solution of the solute in the solvent Solubility is defined as the ability of one substance to dissolve within another substance. What Affects Solubility? One of the factors that has a profound impact on solubility is temperature. Temperature, a measure of the available thermal energy, can increase the solubility of solids in liquids. This phenomenon
