Experiment :12 Vapor Pressure and the Heat of Vaporization Nicole Petersen TA: Ryan Dixon 4/16/2013 Purpose: Use experimental techniques to record temperature and volume data for known and unknown compounds. The liquid and gas are going to be at equilibrium. We will also determine the boiling point for the known and unknown. Then use a graph to calculate the slope and then use Clasius- Clapeyron equation to find the heat vaporization. Procedure: Refer to pages 155-167 of Chemistry 1210 General

Water Transport in Plants Introduction In this lab experiment‚ we set out to examine the different transpiration rates of a plant system in certain environments. Water is transported in a plant by the process of transpiration‚ which is the loss of water through evaporation from the surface of leaves. The stomata in leaves are responsible for the diffusion of water vapor. Transpiration brings water upward through the xylem in the plant. There are certain factors that can affect transpiration

Acetone/Chloroform Liquid-Vapor Phase Diagram Abstract: Liquid-vapor phase of acetone/chloroform was studied through distilling a series of mixtures with different mole fraction. When the mixtures were boiling‚ their vapor was condensed through a water column and collected in a receiving container. Refractive index was collected for starting mixture‚ distillate and residue for each sample. A boiling temperature versus acetone’s mole fraction was constructed to show the liquid-vapor phase diagram. The

Lab 5 – Weather and Climate Change Lab 5 - Demonstration 1: Modeling the Water Cycle POST LAB QUESTIONS 1. Which water cycle processes are represented in this model and by what components? Answer = Condensation and evaporation are represented in the model. Condensation formed inside the jar and under the lid and the warm water evaporated. 2. Which processes are not represented? How could the model be altered to include these processes? Answer = Precipitation and infiltration did not get represented

Water is a chemical compound with the chemical formula H 2O. A water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds. Water is a liquid at standard ambient temperature and pressure‚ but it often co-exists on Earth with its solid state‚ ice‚ and gaseous state‚ steam (water vapor). Water covers 71% of the Earth’s surface.[1] It is vital for all known forms of life. On Earth‚ 96.5% of the planet’s water is found in seas and oceans‚ 1.7% in groundwater‚ 1

Water is a liquid at standard ambient temperature and pressure‚ but it often co-exists on Earth with its solid state‚ ice‚ and gaseous state (water vapor or steam). Water also exists in a liquid crystal state near hydrophilic surfaces. Water is considered a purifier in most religions. Major faiths that incorporate ritual washing (ablution) include Christianity

WATER OUR LIFELINE Water is a transparent fluid which forms the world’s streams‚ lakes‚ oceans and rain‚ and is the major constituent of the fluids of living things. As a chemical compound‚ a water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds. Water covers 71% of the Earth’s surface.[1] It is vital for all known forms of life. On Earth‚ 96.5% of the planet’s water is found in seas and oceans‚ 1.7% in groundwater‚ 1.7% in glaciers and the ice caps of Antarctica

Does This Thing Work? It operates on a 100 year old proven technology called electrolysis. Whenever you place two pieces of metal in water‚ and apply electricity‚ the water separates into it’s basic molecules‚ Hydrogen and Oxygen (H2O). If you look at the picture on the left‚ you will see H2O molecules connected together in their liquid form which is WATER But when you apply electricity (from your car battery)‚ the molecules separate and form a GAS (called HHO) which is a mixture of Hydrogen

to remember as we learn about weather: The sun warms the earth’s surface and therefore all the air above the surface The earth is warmed most at the equator and least at the poles---why? The air above land is warmed more quickly than air above water. Warm air expands and rises‚ creating an area of low pressure; cold air is dense and sinks‚ creating an area of high pressure Factors affecting weather: Temperature Pressure Relative humidity Precipitation Temperature Affected by: Sunrise
