- A gas at T0 and atmospheric pressure fills a cylinder. The gas is transferred to a new cylinder with three times the volume, after which the pressure is half the original pressure. What is the new temperature of the gas? Express your answer in terms of T0⦁ In a standard gas grill propane tank, there is approximately 4,579 mL of propane (C3H8). At a temperature of 55˚C, the tank has a pressure of 1,798 kPa. The tank is cooled to 25˚C and the pressure reduced to 1,025 kPa. What will the new volume be? Remember to pay close attention to the units of temperature before beginning your calculations.A tank initially holds 100 gal of a brine solution containing 1 Ib of salt. At t-0 another brine solution containing 1 Ib of salt per gallon is poured into the tank at the rate of 3 gal/min, while the well-stirred mixture leaves the tank at the same rate. Find the time at which the mixture in the tank contains 2 lb of salt. Select the correct response 1.026 mins. O 1.728 mins. O 0.338 mins. O None
