An air bubble has a volume of 0.490 L at 16 C Submit My Answers Give Up You may want to reference (pages?98-299) Section 8.3 while completing this problem Part C What is the volume, in liters, at-10 C. if n and P do not change? Express the volume to two significant figures and include the appropriate units. VValue Units Submit My Answers Give Up Part D What is the volume, in liters, at 580 K, i n and P do not change? Express the volume to two significant figures and include the appropriate units. VValue Units

Explanation / Answer

Part C: From Ideal Gas equation:

P1V1/n1T1 = P2V2/n2T2

Since, P1 = P2 and n1= n2

The ideal gas equation can be simplified as :

V1 / T1 = V2 / T2

V1 = 0.490 L and T1 = 16 oC = 273 + 16 = 289K

V2 =? And T2 = -10oC = 273 -10oC = 263K

0.49L/289K = V2/263K

V2 = 0.49 L x 263K/289K = 0.456 L

The volume of the gas = 0.46 L (two sign. Fig)

Part D: From Ideal Gas equation:

P1V1/n1T1 = P2V2/n2T2

Since, P1 = P2 and n1= n2

The ideal gas equation can be simplified as :

V1 / T1 = V2 / T2

V1 = 0.490 L and T1 = 16 oC = 273 + 16 = 289K

V2 =? And T2 = 580K

0.49L/289K = V2/580K

V2 = 0.49 L x 580K/289K = 0.983 L

The volume of the gas = 0.98 L (two sign. Fig)
