Question 12 5 pts A sealed gas cylinder on the back of an open truck experiences a temperature change from -19.2°C in a to 39.6 °C as it is driven from North Dakota to Arizona. If the pressure gauge on the tank reads 136.2 atm in North Dakota, what will the gauge read in Arizona? Report your answer below. Do not use scientific notation, or include units. If Carmen adds zeros behind the decimal place in your answer, do not worry. Your response will be graded correctly. Assume the tank did not leak and was not used during its journey. can 12

Answer borh please

Answer 1

1. a) constant a is greater for SO2 than Ne and constant b is greater for SO2 than Ne.

The constant b adjusts for the volume occupied by the gas molecules and it is higher in the case of SO2 as SO2 molecules are bigger than Ne and occupy more volume. Constant a gives the magnitude of attractive forces between the molecules which is greater for SO2 than Ne.

2. At constant volume, pressure is directly proportional to temperature.

P1/P2 = T1/T2

T1 = 273-19.2 = 253.8 K

T2 = 273 + 39.6 = 312.6 K

P1 = 136.2 atm

136.2/P2 = 253.8/312.6

136.2/P2 = 0.812

P2 = 167.7 atm

Pressure in Arizona = 167.7 atm
