Gas Laws Lab Introduction: The four basic physical properties of a gas sample are pressure‚ volume‚ temperature‚ and number of moles. The volume simply indicates the volume of the container since a gas will take up all space available to it. The temperature indicates the average kinetic energy of the gas particles. For gases‚ the temperature must be converted to the Kelvin unit. The pressure of the gas indicates the number of collisions with each other and the wall of the container. The number

(b) At what temperature in degrees Celsius is the volume of the gas 4.0 L if the pressure is kept constant. 2. Calcium carbonate‚ CaCO3(s)‚ decomposes upon heating to give CaO(s) and CO2 (g). A sample of CaCO3 is decomposed‚ and the carbon dioxide is collected in a 250-mL flask. After the decomposition is complete‚ the gas has a pressure of 1.3 atm at a temperature of

Determine the gage pressure of air in the tank if h1=0.2m‚ h2=0.3m‚ and h3=0.46m. Take the densities of mercury‚ water‚ and oil are given to be 13‚600‚ 1000‚ and 850 kg/m3‚ respectively. 2.

Experience There comes a time in each and every human being life when they sacrifice their values and beliefs under the pressure of circumstances or people in order to get accepted by the society. “Salvation” by Langston Hughes and “Shooting an Elephant” by George Orwell are both based on an incident where they had to sacrifice their belief under the pressure of the people around them. The main similarity is that both the narrators went through a situation in their life‚ where
