1. The volume of a gas with a pressure of 1.2 atm increases from 1.0 L to 4.0 L. What is the final pressure of the gas, assuming constant temperature?2. The gas with an initial volume of 24.0 L at a pressure of 565 mmHg is compressed until the volume is 16.0 L. What is the final pressure of the gas, assuming the temperature does not change?
You have a tank of compressed helium that has a volume of 12 L and a pressure of 12 atm. You filled party balloons that hold 3 liters each, here in San Francisco. How many party balloons could be filled? The temperature and n are constant. Remember the tank holds 12 L of helium even at atmospheric pressure.
2b) (10 points) If the pressure gauge at the bottom of the tank reads 100 kPa, what is the pressure in the Air at the top of the tank if the liquid temperature is 35°C? Give answer in psi and KPa. You must show your work to get full credit. ir 3 m 2m Oil (S 0.8) 3 m Water kPa
A compressed air tank carried by scuba divers has a volume of 9.0 L and a pressure of 140 atm at 20∘C. If the gas was instead in a cylinder with a floating, massless, frictionless piston, what would the volume of the gas be (in liters) at STP? Express the volume in liters to two significant digits.
