Question

container with a volume of 4.35 x 10t L,an internal pressure of 1.00 atm, and an internal etare of 15.00 C ls washed off the deck of a ship and sinks to a depth where the pressure is 375 temperature is 3.00PC. What will the voume of the gas inside be when the containe mpera and the breaks under the pressure at this depth? 7 Caco, decomposes at 1200 Cto form COrgas and Cao. if 25 L ef CO, are collected st 1200°c, what will the valume of this gas he after it cools to 25 C? 6.DL of gas in a ston at a pressure of 1.0 atm are compressed until the volume is 35 L what is the new pressure inside the piston? 9 A 75 L container holds 62 moles of gas at a temperatiue of 215 Whst is the pressure in atmospheres inside the container? 10. A ballon that can hold 85 L of air is inflated with 3.5 males of gas at a pressure of 1.0 atmosphere What is the temperature in C of the balloon?

Explanation / Answer

Ans 7 : Using the ideal gas law , pV = nRT,

we get the relation as :

V1 T2 = V2 T1

V1 = 25 L

T1 = 1200oC = 1473.15 K

T2 = 298.15 K

So putting all the values we get :

25 x 298.15 = V2 x 1473.15

V2 = 5.06 L
