Question

EXP #12: PRE-LAB EXERCISE 1. A sample of a gas has a pressure of 23.8 PSI and a volume of 250 mL. If the volume is increased to 1.50 L, what will the new pressure be? Show your calculations. 2. Doctor Stanley Schmozawitz measures the tire pressure on his recumbent bike one morning when it is 41.0 degrees Fahrenheit (5.0 degrees Celsius) and finds it to be 55 PSI. Later that afternoon, it is 77.0 degrees Fahrenheit (25.0 degrees Celsius), what should the pressure be at that time of the afternoon? Show your calculations. Scanned with CamScanner

Answer 1

O By Boyle's low, P, U, = P2 V 2 Here, P,= 23.8 psi , V, = 250mL Pe=? Vza 1.50L = 1500mL By putting values, we get PE 23.8 Psi x 250mL 3.97 Psi 1500ML
