A steel bomb having a volume of 575 cm^3 is filled with air at 28degreeC and 0.8

Question

A steel bomb having a volume of 575 cm^3 is filled with air at 28degreeC and 0.85 atm. If the bomb was filled with 575 cm^3 of air at 2.0 atm of pressure, what is the temperature of the air? A sealed glass vessel with a 50.0 L volume is filled with argon gas at 22degreeC and 1.0 aim. If the vessel is heated to 225degreeC, what is the new pressure of the argon gas? A glass ampule is filled with helium gas and is scaled at a pressure of 1.0 atm and 25degreeC. If the ampule is stored in a -80degreeC freezer, what is the new pressure of helium within the ampule? A balloon is filled to a volume of 5.8 L with 2.5 moles of helium gas. If 1.4 L of helium is added to the balloon, how' many moles of helium gas arc now- in the balloon? How many moles of helium were added to the original 2.5 moles? A balloon is filled to a volume of 1.6 L with 0.5 moles of helium gas. If 1.4 moles of helium jrc added to the balloon, what is the new volume? At STP, the volume of a sample of O_2 gas is 24.7 L. What will the volume be if the tempei.is raised to 39degreeC and the pressure is raised to 5.4 atm? At SIT, the volume of a sample of H_2 gas is 9.6 L. If the temperature is lowered to -56degree the volume is increased to 10.4 L, what is the new pressure? A 1 mol sample of radon gas is at STP. If the pressure is increased to 25 atm and the volume decreased to 17.8 L, what is the new temperature of the 1 mol sample?

Explanation / Answer

8)

V1= 575 cm3

T1 = 28C = 28+273 = 301 K

P1 = 0.85 atm

V2 = 575

P2 = 2 atm

T2 = ??

apply Gas law ratio law

P2/T2 = P1/T1

T2 = T1*(P2/P1) = 301*2/0.85= 708.23 K
