PPT-Temperature, Pressure, and Density

Danielle Hettmann and Chris Saleh SYST460 Fall 2011 Static temperature measure of the temperature at the surface of the aircraft Ambient temperature measure of the temperature of the air in the region surrounding the aircraft. 0 For CH OH the normal boiling point is 646 For C OH the normal boiling point is 783 brPage 2br Vapor Pressure and Boiling Point The vapor pressure of a liquid is related to its heat of vaporization vap through the ClausiusClapeyron Equation If P 1 Principles Density The density pronounced rho of an object is the ratio of its mass to its volume Since very few substances have exactly the same density this property can be used to identify an element or compound Buoyant Force When you are swim What . is an advantage of composites that aids in lowering maintenance costs?. What is a potential disadvantage of composites in a hot climate or conditions?. Describe the care maintainers must utilize with paint strippers on composite materials?. Density Controls. Controlled by:. 1.) Temperature. 2.) Salinity. 3.) Pressure. Density increases with increasing salinity. Density increases with decreasing temperature.. Density increases with increasing pressure.. 2. The denser the atmosphere…. the greater its weight, and . the greater its air pressure.. 3. atmospheric pressure -. . a.k.a. .; . barometric pressure or air pressure.. the pressure due to the weight of the overlying atmosphere.. Hint, don’t forget to find the volume of the ice first!. ). Warm Up: Density of Ice. Does the density of ice you calculated make sense? Why or why not?. Warm Up: Density of Ice. Draw a dot diagram to compare the density of ice and water.. Perfect conductors. carry charge instantaneously from here to there. Perfect insulators. carry no charge from here to there, ever. Real substances . always. have. some density . n . of charges . q. This tool can measure the temperature, volume, and pressure of a gas. What is temperature?. All particles in all things are moving at all times, but some faster than others. Temperature measures the average speed of the particles in something. (. Gay-Lussac’s Law). Gay-Lussac’s law: . When . the . Kelvin temperature . of a . gas doubles . at constant volume and amount of gas, the pressure also doubles.. Learning Goal . Use the temperature–.

The horizontal distribution of air pressure on the globe is studied on the basis of Isobars. If we look at the globe then it appears that there is certain definite system of high and low pressure.. If, for generalization, the globe is considered to be homogeneous (either of land or water), then there should be regular and systematic zonal distribution of high and low pressure but the regularity of pressure belts is distributed due to unequal distribution of land and water on the globe. .

This . is a direct result of density. Since, density changes with differences in temperature, compression, substances in solution and substances in suspension; the weight of a cubic foot of natural water is not always the same. .
