Evaporation When water goes from the bodies of water on the Earth back into the atmosphere‚ evaporation has occurred. This cycle is driven by the energy from the sun. When water vapor cools as it undergoes the process of condensation. Condensation is the process of water going from the gas phase into

DAMS: GOOD OR BAD Introduction The unequal availability of resources leads to the development of methods to store them. Water as the prime resource for survival has been the determining factor for human settlements‚ been the sole reason for communities to thrive and for long formed the basis for wars. In locations where the appearance of rainfall is scanty and unreliable‚ the need to store water has given rise to the creation of ‘tankas’‚ creation of man-made lakes and similar reservoirs

components that are indistingushable with each other e.g. (colloids) while Heterogenous mixtues ’ components can be distinguished from each other e.g. (suspensions). Mixtures can be separated by physical changes through distillation‚ decantation‚ evaporation‚and the use of magnet. Materials and Methods The reagents that we used are the following: Iron fillings‚ Distilled Water‚ Sodium Chloride (NaCl)‚ Sulfur. The equipments:100ml Beaker‚ Bunsen Burner‚ watch Glass‚ Stirring rod‚ Magnet‚ Mortar

Chapter 6 Integumentary System 6.1 Introduction The skin‚ the largest organ in the body‚ and its accessory structures constitute the integumentary system. 6.2 Skin and its tissues Skin is a protective covering‚ helps regulate body temperature‚ houses sensory receptors‚ synthesizes chemicals‚ and excretes wastes. It is composed of an epidermis and a dermis separated by a basement membrane. A subcutaneous layer‚ not part of the skin‚ lies beneath the dermis. The subcutaneous layer is composed of

Hurricane Katrina Hurricanes start off as tropical depressions (centres of low atmospheric pressure) over tropical oceans. Three things must happen for a hurricane to form. A continuous evaporation and condensation cycle must take place; there must also be patterns of winds that are characterized by the converging winds‚ and a difference in air pressure between the surface and high altitude. In the warm waters of the eastern Atlantic‚ water vapour rises from the ocean and then cools forming clouds

ABSTRACT A molecular diffusion experiment was conducted with the goal of determining the diffusion coefficient of acetone into air. For this experiment‚ acetone was placed in a capillary tube and was allowed to diffuse into 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

on the intermolecular forces: -wetting (water absorbed by matter) -surface tension -capillary action -melting and boiling points -cohesion (attraction between like molecules) -adhesion (attraction between unlike molecules) -solubility -evaporation -intermolecular forces are much weaker than covalent bonds ex. if covalent bonds are assigned a strength of 100‚ then intermolecular forces are between 0.001 to 15. -there are 3 types of intermolecular forces: Dipole-Dipole‚ London Dispersion

05.09 Module Five Review and DBA 05.01 Four Phases of Matter * Matter exists in different phases‚ also called states‚ which include solid‚liquid‚ gas‚ and plasma. These phases can be distinguished at the molecular level by how the particles are held together. * Solids * In the solid phase‚ the intermolecular attraction between particles of matter is strong enough to hold all the particles together in a fixed three-dimensional arrangement. Because of the rigid arrangement of particles
