the pressure of the oxygen gas inside a consister with a fixed volume is 5.0atm at 15 degree Celsius. what is the changes to 263k? assume the amount of gas remains constant.

a beach ball is inflated to a volume of 25L of air at 15 degree Celsius. during the afternoon, the volume increases by 1L. what is the new temperature outside?

a birthday balloon is filled to a volume of 1.5L of helium gas in an air conditioned room ay 293k. the balloon is taken outdoors on an warm day where the volume expands to 1.55L. Assuming the pressure temperature outside in Celsius.

atmospheric pressure on the peak of Kilimanjaro can be as low as 0.20atm. if the volume of an oxygen tank is 10.0L, at what pressure must the tank be filled so the gas inside would occupy a volume of 1.2X103L at this pressure?

a whether balloon with a volume of 2000L at a pressure of 96.3kPa rises to an altitude of 1000m. where the atmospheric pressure is measured to be 60.8kPa. assuming there is no change in the temperature or the amount of gas. calculate the weather balloons final volume.

How many grams of O2 will completely react with 49.0 g PH3?

Silver is a metal commonly used in jewelry and photography. It crystallizes with a face-centered cubic unit cell 0.407 nm on an edge. Solve for: a) atomic radius of silver, b) volume of a single silver atom, c) density of a single silver atom.

A major ore of bismuth (III) sulfide, Bi_2S_3. By roasting in air, it is converted to the corresponding oxide; sulfur dioxide is a byproduct. What volume of SO_2 at 25 degrees Celsius and at 1 atm is formed when 0.5 tons (0.5 x 10^6 g) of ore containing 2.5% Bi_2S_3? (Hint: convert the mass of the Bi_2S_3 present in the ore to moles of Bi_2S_3 and then covert to moles of SO_2. Then use the ideal gas law [pV=nRT] to convert to the volume of SO_2) [NOTE: underscores (_) refer to subscripts, while (^) indicates superscripts].
