Question

Show work clearly. 1. A balloon filled with 0.500 L of air at sea level is submerged in the water to a depth that produces a pressure of 3.25 atm. What is the volume of the balloon at this depth? 2. If the volume of a gas container at 32 C changes from 1.5S L to 755 mL, what will the final temperature be? 3. A small bubble rises from the bottom of a lake, where the temperature and pressure are 4°C and 3.0 atm, to the water's surface, where the temperature is 25°C and the pressure is 0.95 atm. Calculate the final volume of the bubble if its initial volume was 2.1 mL 4. A 325 mL sample of gas is initially at a pressure of 721 mm Hg and a temperature of 32°C. If this gas is compressed to a volume of 286 mL and the pressure increases to 901 mm Hg, what will be the new temperature of the gas?

Explanation / Answer

1.

Formula, According Boyle's law,

P1 V1 = P2 V2

1.00 * 0.500 = 3.25 * V2

V2 = 0.154 L

2.

Formula, According Charle's law,

V1/ T1 = V2 / T2

1.55 / 305.15 = 0.755 / T2

T2 = 148.64 K

t2 = - 124.5 0C

3.

Formula,

P1 V1 / T1 = P2 V2 / T2

3 * 2.1 / 277.15 = 0.95 * V2 / 298.15

V2 = 7.13 mL

4.

Formula,

P1 * V1 / T1 = P2 V2 / T2

721 * 325 / 305.15 = 901 * 286 / T2

T2 = 335.57 K

t2 = 62.42 0C
