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...
What volume (in mL) will a sample of F2 gas occupy in a syringe at 5.5 atm, if the F2 has a volume of 25.0 mL at 1.2 atm?
1. A gas sample occupying a volume of 28.5 mL at a pressure of 0.933 atm is allowed to expand at constant temperature until its pressure reaches 0.377 atm. What is its final volume? 2. Under constant-pressure conditions a sample of hydrogen gas initially at 35.00°C and 6.30 L is cooled until its final volume is 1.50 L. What is its final temperature in C?
A 0.75g sample of oxygen gas has a volume of 286mL sample of under a pressure of 2026.5millibars. Show work. a. How many moles of oxygen are in this sample? b. What pressure is the gas under in units of atmospheres? c. What is the volume of the sample in Liters? d. What is the temperature of the sample in degrees Celcius?
5. A sealed syringe filled with air has a volume of 69 mL at 25°C. When the syringe is placed in a deep freezer the volume changes to 5.3 mL. What is the temperature in the deep freezer? Report finalayswer in degree Celsius. Assume all other conditions are kept constant. b pts
Part A A syringe containing 1.35 mL of oxygen gas is cooled from 92.8 ∘C to 0.9 ∘C. What is the final volume Vf of oxygen gas? Part B A cylinder with a moveable piston contains 0.540 mol of gas and has a volume of 300 mL. What will its volume be if an additional 0.279 mol of gas is added to the cylinder? (Assume constant temperature and pressure.)
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.
The syringe shown at right contains nitrogen gas. The syringe has a movable piston of mass M. At the bottom, the syringe is closed by a valve, so that no gas may enter or leave the syringe. (Neglect friction between the piston and the wall of the syringe. Assume that nitrogen gas behaves like an ideal gas.) Initially the syringe is in thermal equilibrium with an ice-water bath. The pressure and volume of the gas inside the syringe are Pinitial...
