The cause of atmospheric pressure is exerted equally in all directions up‚ down‚ and sideways. 4. The two types of barometers measure atmospheric pressure ‚ atm ‚ millimeters and or inches of mercury and the millibars mb. Therefore‚ the two barometers are the mercurial and the aneroid. 5.

test is performed to determine the magnitude and rate of volumes decrease that laterally confined soil specimen undergoes when subjected to different vertical pressures. From the measured data‚ the consolidation curve can be plotted. This data is useful in determining the compression index‚ the recompression index and the preconsolidation pressure of the soil. In addition‚ the data obtained can also be used to determine the coefficient of consolidation and the coefficient of secondary compression of

volume of the football starts to decrease. Boyle’s Law describes how the pressure of the gas tends to decrease as the volume of a gas increases. As the pressure decreases‚ the volume of the gas increases. The bubbles exhaled by the fish grow as it approaches the surface of the ocean. When the fish is exhaling out the air‚ the bubbles tend to become bigger and bigger. As the bubbles start to approach the sea surface‚ less pressure will be put on the bubbles‚ so the volume of the bubbles start to increase

As well‚ perpetrators of fraud can be motivated by a perceived opportunity to commit fraud and the ability to rationalize that what they are doing is not wrong. Their motivations are usually combined into the fraud triangle of perceived pressure‚ perceived opportunity‚ and rationalization. 3. The fraud triangle includes three elements that almost always must be present in order for someone to commit fraud: a perceived pressure‚ a perceived

Continue this process until data is obtained for at least six different volume and pressure combinations. Be sure to use a range of volume measurements to help you better compare the relationship of volume and pressure. Please record the data below in the data chart.

By using the ideal gas equation‚ and plugging the slope value from the graph into the Clausius-Claypernon equation‚ enthalpy of vaporization was determined to be 10kJ/mol. The percent error was determined to be 76.0%. Introduction: The purpose of this lab is to investigate vapor pressures and the partial pressure of gas produced from liquids at different temperatures. These pressures vary at different temperatures
