14. A gas laws experiment was conducted in the physics lab. During this experiment, the gas pressure of an isolated gas in an adjustable syringe was measured using a gas pressure sensor as the volume of the syringe was varied. The pressure vs volume for the graph for the experiment is shown below, as well as the corresponding curve fit generated. NOTE: The gas temperature was a constant 23.5°C during this experiment Express value of the...
1. A long cylindrical gas-tight tube, with a sound source at one end and sensor at the other, was constructed to measure the speed by recording the time it take a sound wave to travel the length of the tube (see diagram). i. Initially, the tube was filled with air at atmospheric pressure (P=1.012x105Pa & T=295.2K). When a sound wave is produced by the source, the elapsed time for the wave to reach the sensor was 3.64x10-3s. Determine the length of...
A gas is placed in a 5.0-mL syringe. It exerts 149 mm Hg of pressure on the inside walls of the syringe. The syringe's plunger is pressed, reducing the volume of the syringe to 2.8 mL. The cap was not removed from the syringe, so none of the gas escapes. Assuming the temperature of the gas does not change, use Boyle's law (below) to determine the pressure of the compressed gas. P_1 V_1 = P_2V_2 mm Hg
For the gas constant, use R = 8.314 J/mol-K For Avogadro's number, use N_0 = 6.022 times 10^23 molecules. Be careful of units! All the conversions you need are in the information section of the lab. Suppose the volume of the syringe is 47.5 cc. You measure the pressure as 1.58 atm, and the temperature as 19.8 degree C. Assume: the diameter of the plunger on the syringe is 1.44 cm. Find the number of moles of gas in the...

Pressure and Temperature at Constant Volume A gas cannister, in which the pressure is initially 1.70 atm at 32°C, is heated to 394°C. What will be the new pressure inside the cannister? (Note: First, convert the temperature to Kelvin.) Submit Answer Tries 0/5
An isolated gas (nitrogen, N2), at initial temperature of 22.7 degrees Celsius, is expanded from as initial volume of 0.750L to 1.450L at constant pressure, P=132kPa. During this process the gas absorbs 318.5J of heat. i. Calculate the work output by the system during this expansion ii. Estimate the specific heat capacity of the gas for this process. Express your answer in J/kg*K.

3. Nitrogen gas was collected in a eudiometer during a chemistry experiment by displacement of water. When the levels of water inside and outside the eudiometer were adjusted to be the same, the volume of the collected gas was found to be 85.2 mL. The water temperature was 24°C and the barometric (atmospheric) pressure was found to be 764.0 mm Hg. What would be the volume of dry nitrogen gas at STP?
During an experiment, 1.00 moles of argon gas (a real gas) undergoes a compression such that the final volume is ½ of the initial volume. The initial volume and temperature of the gas are 2.53 m3 and 298 K, respectively. After the compression is complete, the temperature of the gas is 215 K. If the argon behaves according to the equations of state: P(V-nb) = nRT where, b = 0.115 m3/mol. and the molar heat capacity at constant pressure is...
