Determine the pressure of a gas in a 15-mL syringe at 10 psi when its volume...
If the pressure on the syringe is increased to 22.1 psi , but the temperature remains constant, what is the volume of the oxygen gas in the syringe? A sealed syringe contains 6 cc of oxygen gas under 14.7 psi of pressure.
A sealed syringe contains 6 cc of oxygen gas under 14.7 psi of pressure. If the pressure on the syringe is increased to 44.1 psi , but the temperature remains constant, what is the volume of the oxygen gas in the syringe?
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
1. Why are sharp knives more effective than dull knives? (Hint: Think about the definition of pressure.) 2. Name 6 possible units of pressure. 3. Convert 30°C to Kelvin. 4. Draw a manometer and a barometer and explain how they both work. 5. Sometimes leaving a bicycle in the sun on a hot day will cause a blowout. Why? 6. A 2.50-L volume of hydrogen measured at -196 °C is warmed to 100 °C. Calculate the volume of the gas...
A sample of gas occupies a volume of 10.5 L when the pressure is 14.3 psi. Use Boyle’s Law to calculate the pressure (psi) when the volume is increased to 14.5L. Show the calculation
4. A Gas at 1.00 atm is contained in a 30 mL syringe. Calculate the pressure of the gas if the syringe volume is compressed to 5 mL without allowing any gas to leak. 5. Would you expect the volume of gas contained in a balloon to increase or decrease if it is exposed to lower temperatures? A balloon containing 3.50 L of gas at room temperature, 20 °C, is submerged into a vat of liquid nitrogen. The temperature of...
A home propane tank at is empty when its internal pressure is psi psi absolute pressure. If its volume of 125 ft^3 is filled to the point where its pressure is 75 psi absolute pressure(with all propane staying in the gaseous phase), how much mass has beenadded? Note that the molecular weight of propane is the same as that of carbondioxide, so the gas-specific constant for carbon dioxide given in the class text appendix can be used for propane. Also,...
Question 14 Not yet graded/2 pts A gas with a volume of 50 mL when pressure is 15 atm and the temperature is 298K. What is the pressure when the gas increased to 150 mL at 298K? Your Answer: 5 atm Question 15 Not yet gra led/5 pts Free Response Calculate the moles of carbon dioxide produced at 22°C and 3 psi when 1.41 g of calcium carbonate reacts with 15.0 mL of 2M hydrochloric acid. Your Answer: 0.123 L
The pressure of a gas is 750.0 torr when its volume is 400.0 mL. Calculate the pressure (in atm) if the gas is allowed to expand to 600.0 mL at constant temperature.
03. The sample of gas in the figure below has a volume of 15.0 mL at a pressure of 13.0 psi. Determine the pressure of the gas at a volume of 7.5 mL, using: (5.0, 39.0) P (psi) (10.0, 19.5) TITTO (15.0, 13.0) (20.0.9.8) (25.0, 7.5) (30.0, 6.5) 5 10 25 30 15 20 V (mL.)
