Question:
What will happen to the volume of a bubble of air found under water in a lake, where the temperature is 15oC and the pressure is 1.5 atm, if the bubble rises to the surface where the temperature is 25oC and the pressure is 1.0 atm?

The Correct Option is B
Solution and Explanation
Explanation:
p1V1/T1 = p2V2/T2p1 = 1.5 atmT1 = 15oC = (15 + 273) K = 288 Kp2 = 1.0 atmT2 = 25 + 273 = 298 KTherefore, 1.5 x V1/288 = 1 x V2/298 V2 = 1.6V1
p1V1/T1 = p2V2/T2p1 = 1.5 atmT1 = 15oC = (15 + 273) K = 288 Kp2 = 1.0 atmT2 = 25 + 273 = 298 KTherefore, 1.5 x V1/288 = 1 x V2/298 V2 = 1.6V1
