PLEASE ANSWER D, E and F. Show your work. D. A gas sample has a volume of 0.256 L with an unknown temperature. The same gas has a volume of 0.198 L when the temperature is 32 ˚C, with no change in the pressure or amount of gas. What was the initial temperature in degrees Celsius, of the gas? (You will get your answer first in Kelvin, then convert that temperature to degree Celsius). E. Home oxygen tanks can be dangerous if they are heated because they can explode. Suppose an oxygen tank has a pressure of 120 atm when the room temperature is 25 ˚C. If a fire in the room causes the temperature of the gas inside the tank to reach 402 ˚C, what is its pressure in atmospheres if the volume and amount of gas do not change? The oxygen tank may rupture if the pressure inside exceeds 180 atm. Would you expect the tank to rupture? F. A weather balloon has a volume of 35 L at sea level (1.0 atm). After the balloon is released, it rises to where the air pressure is 0.75 atm. What will the new volume of the balloon be?
