Consider a gas cylinder with a volume of 140-L tha contains a pure noble gas element at 25 degrees celsius and a pressure of 2200 psi to answer the following questions. a. What is the pressure in atomospheres (atm)? b. What is the temperature in Kelvins (K)?

As 1 g of (lie radioactive element radium decays over 1 year. k produces 1.161018 alpha particles (helium nuclei). Each alpha particle becomes an atom of helium gas. What is the pressure ¡n pascal of the helium gas produced if it occupies a volume of 125 mL at a temperature of 25 C?

One way to state Boyle’s law is All other things being equal, the pressure of a gas is inversely proportional to its volume. (a) What is the meaning of the term inversely proportional? (b) What are the other things that must be equal?

A 20.0L stainless steel container at 25C was charged with 2.00 atm of hydrogen gas and 3.00 atm of oxygen gas. A spark ignited the mixture, producing water. What is the pressure in the tank at 25C? If the exact same experiment were performed, but the temperature was 125C instead of 25C, what would be the pressure in the tank?

A typical barometric pressure in Denver, Colorado, is 615 mm Hg. What is this pressure in atmospheres and kilopascals?

Consider two different containers, each filled with 2 moles of Ne(g). One of the containers is rigid and has constant volume. The other container is flexible (like a balloon) and is capable of changing its volume to keep the extemal pressure and internal pressure equal to each other. If you raise the temperature in both containers, what happens to the pressure and density of the gas inside each container? Assume a constant extemal pressure.
