Answer

Explanation:

Step1: Recall solubility rules

Solubility of gases in liquids increases with high pressure and low temperature. Solubility of solids/liquids in liquids may increase or decrease with temperature change depending on the nature of the solute - solvent interaction. For gases in this context, high pressure (solution W) and low temperature (solution X) increase solubility. High temperature (solution Y) decreases gas solubility and low pressure (solution Z) decreases gas solubility.

Step2: Analyze options

  • Option 1: Solutions X (low - temp) and Z (low - pressure) - Z has low solubility due to low pressure, so this is incorrect.
  • Option 2: Solutions Y (high - temp) and Z (low - pressure) - Both Y and Z have factors that decrease solubility, so this is incorrect.
  • Option 3: Solutions W (high - pressure) and Y (high - temp) - Y has decreased solubility due to high temperature, so this is incorrect.
  • Option 4: Solutions W (high - pressure) and X (low - temperature) have factors that increase solubility compared to Y (high - temperature) and Z (low - pressure). This is correct.

Answer:

Solutions W and X have greater solubility than solutions Y and Z.
