Part Two: Calculations using the Gas Laws. Describe each relationship in one sentence. 1. A container filled with air at a pressure of 1.02 atm has a volume of 2.75 L. If the volume changes to 3.25 L, what is the new pressure? Describe the relationship between pressure & volume. 2. A sample of gas has a volume of 2.8000 L. When submerged in ice water at T = 0.00 °C (273.15 K), its volume decreases to 2.5700 L. What...

3. Consider a gas with the properties of air. The gas begins at a state described by a pressure of I5 atm and 600 K. If the gas is taken to a new state in which the temperature is 400 K and the pressure is 1 atm, determine the entropy change in two ways: 1. use an isentropic expansion from the first state down to a pressure of 1 atm and then reversible heating from the resulting temperature to the...

For the reaction A(aq) + BB(1) - C(s) + (aq) the equilibrium constant, K, can be written as PoD K- A When calculating the equilibrium constant, aqueous solutes must be expressed in moles per liter (M), and gases must be expressed in pressure as bars. This is because they are dimensionless ratios of the actual concentration or pressure divided by standard state concentration, which is M for solutions and 1 bar for gases. these are the only units of concentration...
