The ideal gas law from chemistry says that for n moles of an ideal gas, its pressure, volume, and temperature are all related by the following equation: PV = nRT. Here R = 0.0821 is a constant, P is the pressure of the gas in atmospheres (atm), V is its volume in liters (L), and T is its temperature in Kelvin (K). Suppose that you are working with a pressure chamber that contains 3 moles of an ideal gas (so n = 3 mol, and this is a constant). The pressure chamber allows you to compress, heat, and chill the gas, so you can change its pressure P, its volume V, and its temperature T. At a certain instant, the volume of the gas is 5 L and it is being decreased by 2 liters per minute, the gas is being heated up at a rate of 20 Kelvin per minute, and the pressure of the gas is 8 atm. How fast is the pressure changing at this instant, and is it increasing or decreasing? Include the correct units in your answer. (Note: You do not need to keep track of the units throughout your whole calculation. However, if you would like to do that, the units for the constant R are as follows: R = 0.0821 L atm / (mol K))
