When air expands adiabatically (without gaining or losing heat), its pressure P and volume V are related by the equation PV 1.4 = C, where is a constant. Suppose that at a certain instant the volume is 500 cm and the pressure is 80 kPa and is decreasing at a rate of 10 kPa/min. At what rate is the volume increasing at this instant?

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation PV = 8.317, where P is measured in kilopascals, V in liters, and T in kelvins. Use differentials to find the approximate change in the pressure if the volume increases from 10 L to 10.3 L and the temperature decreases from 345 K to 335 K. (Note whether the change is positive or negative in your answer. Round your answer to two decimal...

The pressure of a gas (P) is monitored as the volume is increased by various amounts (AV). In an experiment, the initial volume V. is unknown. Boyle's law says that V.+AV=k (1) where V. and k are positive constants. If we were to plot y vs. x, where y= AV and 2 = (* Then we expect to get a straight line (y = mx + b), where • slope = m = y-intercept = b = If the unit...

The ideal gas law (PV=nRT) describes the relationship among pressure P, volume V, temperature T, and molar amount n. Fix n and V When n and V are fixed, the equation can be rearranged to take the following form where k is a constant: PT=nRV=k or (PT)initial=(PT)final This demonstrates that for a container of gas held at constant volume, the pressure and temperature are directly proportional.The relationship is also called Gay-Lussac's law after the French chemist Joseph-Louis Gay-Lussac, one of...
