Answer
TRUE: Water becomes MORE soluble for SOLIDS and LESS soluble for GASES False: The other three statements are incorrect according to principles of science related to solubility versus temperature and pressure.
Explanation
## Step1:First, we need to understand what the term 'solubility' represents. In the context of chemistry, solubility refers to the maximum quantity of a solute which can dissolve in a certain volume of solvent at a given temperature.## Step2:Next, the relationship between solubility, temperature, and type of solute needs to be perceived. Genuinely, as the temperature increases, the solubility of most solid solutes in a liquid surge as internal energy of molecules escalates adequate to unsettle the phase integral energy between solute particles permitting them to dissolve. In contrast, the case of gases is opposite; their solubility in liquid lessens as temperature increases, demonstrated in Henry's law.## Step3:Within these contexts we go trough the proposed statements: First statement prefers solubility increases irrespective of the solute which isn't accurate for gases. The second statement is correct as per established hypotheses indicating increasing solubility of solids and decreasing solubility of gases with temperature rise. The last two statements are fallacious; Third one professes unchanging solubility with changing conditions which isn't true as mentioned above in solubility dependance on condition changes. In last one, pressure indeed plays a vital role in regulating solubility of gases, boasting directly proportional connection. Increased pressure conditions impede gases to scatter leading to higher solubility.
