Methane, which constitutes the majority of natural gas, is sometimes stored in condensation tanks in an oil and gas field. If the vaporirzed methane above the liquid is at a temperature of 28.9˚C on a hot summer day with a density of 2.05 kg/m3, at what pressure in Pascals would the gas be? The specific gas constant for methane is 518 J/(kg K).

The absolute pressure in your car tires is 3.7 × 105 Pa at a temperature of 35.0°C when you drive it onto a ferry boat to Alaska a. What is the absolute pressure of the tires, in pascals, later when the temperature has dropped to -40.0°C? Assume the volume of each tire does not change.

A large cylindrical tank contains 0.760 m3 of nitrogen gas at 20.0 ∘C and 1.45×105 Pa (absolute pressure). The tank has a tight-fitting piston that allows the volume to be changed. What will be the pressure if the volume is decreased to 0.410 m3 and the temperature is increased to 159 ∘C? Express your answer in pascals.

Problem 5:   n = 3.9 moles of an ideal gas are pumped into a chamber of volume V = 0.094 m3. Part (a)  The initial pressure of the gas is 1 atm. What is the initial temperature (in K) of the gas?  50% Part (b)  The pressure of the gas is increased to 10 atm. Now what is the temperature (in K) of the gas?

An automobile tire is inflated with air originally at 10.0°C and normal atmospheric pressure. During the process, the air is compressed to 27.0% of its original volume and the temperature is increased to 38.0°C. (a) What is the tire pressure in pascals? Use the ideal gas law to find the pressure inside the tire from its volume and temperature. Pa(b) After the car is driven at high speed, the tire's air temperature rises to 85.0°C and the tire's interior volume increases by 3.00%. What is the new tire pressure (absolute) in pascals?

A balloon is filled with helium gas at atmospheric pressure (1 atm) until its volume is 800 m³. The helium gas is then transferred to cylinders that have a volume of 2.3 m³ at a pres- sure of 13.3 atm. Calculate the number of cylinders used. Assume that the temperature of the helium gas remains constant. (1 atm = 1.013 × 105 Pa).

A quantity of an ideal gas is stored in a rigid container of constant volume.  If the gas is originally at a temperature of 23.1 oC, at what temperature will the pressure of the gas double from its original value?  Give your answer in degrees C.

When air expands adiabatically (without gaining or losing heat), its pressure P and volume V are related by the equation PV14 = Cwhere C is a constant. Suppose that at a certain instant the volume is 670 cubic centimeters and the pressure is 99 kPa and is decreasing at a rate of 7 kPa/minute. At what rate in cubic centimeters per minute is the volume increasing at this instant? cm3 min (Pa stands for Pascal -- it is equivalent to one Newton/(meter squared); kPa is a kiloPascal or 1000 Pascals. )
