The ideal gas law relates the pressure P , volume V , and temperature T of a fixed number of molecules of a gas in a container via: PV= nRT where R =.082 is constant, using pressure units atm , volume units L , and temperature units K . Suppose there are a fixed amount n =12 moles of oxygen in a container. Determine the rate at which the pressure is changing when the pressure is 4.1 atm and the temperature is 22.5K , if the volume is being decreased by 0.3 L/s and the temperature is being increased by 0.06 K/s.
