the basic units of pressure. The basic units of pressure are atmospheres‚ psi‚ mm of Hg‚ torrs‚ and Pascals (Newtons per square meter) Know the difference between gage and atmospheric pressure. Atmospheric pressure is the pressure exerted by the earth’s atmosphere at any given point‚ being the product of the mass of the atmospheric column of the unit area above the given point and of the gravitational acceleration at the given point. Gage pressure is measured on a pressure gage and is above or

Boyle’s Law Experiment Aim To show that Pressure is proportional to the inverse to volume Method A gas syringe was attached to a pressure sensor. The pressure sensor was calibrated‚ assuming the atmospheric pressure at the time of the experiment was 100kPa. Differing volumes of gas were created in the gas syringe and they were recorded as were the corresponding values of pressure at that particular volume. The volume was varied between 20cm3 and 75cm3. Results A set of readings was obtained

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.

mass‚ pressure (P)‚ thermodynamic temperature (T) and volume (V). These properties are related to each other and the state of a gas is determined by their values. The three laws are derived from these properties. Discussion Boyle’s gas law Boyle’s law relates the volume and pressure of an ideal gas. It states that when the temperature of a given mass of a confined gas is held constant‚ its pressure and volume are inversely proportional. In other words‚ the product of absolute pressure and volume

100kPa and in the room temperature. This equation shows the product of the pressure(P) and volume(V) equals to the product of the number of moles(n)‚ ideal gas constant (R‚ 8.31451J/molK)‚ and the temperature in Kelvin(T). In order to calculate ‘n’‚ several assumptions must be made. As the substance goes through the boiling water bath‚ the beaker is assumed to only contain the vaporized from of the
