For each system listed in the first column of the table below, decide (if possible) whether the change described in the second column will increase the entropy S of the system, decrease S, or leave S unchanged. If you don't have enough information to decide, check the "not enough information" button in the last column. Note for advanced students: you may assume ideal gas and ideal solution behaviour. System 1.0 g of potassium chloride (KCl) and 2.0 L of pure water at 14 °C. A mixture of argon (Ar) gas and nitrogen (N₂) gas at 1 atm and -18°C. A solution made of potassium chloride (KCl) in water, at 14° C. Change The potassium chloride is dissolved in the water. An additional 2.0 L of pure N₂ gas is added to the mixture, with the pressure kept constant at 1 atm. 50. mL of pure water is added to the solution.

For each system listed in the first column of the table below, decide (if possible) whether the change described in the second column will increase the entropy S of the system, decrease S, or leave S unchanged. If you don't have enough information to decide, check the "not enough information" button in the last column. Note for advanced students: you may assume ideal gas and ideal solution behaviour. System 1.0 g of potassium chloride (KC1) and 2.0 L of pure water at 14 °C. A mixture of argon (Ar) gas and nitrogen (N₂) gas at 1 atm and - 18°C. A solution made of potassium chloride (KCl) in water, at 14°C. Change The potassium chloride is dissolved in the water.
