Increasing the temperature generally
decreases the solubility of a solid in a liquid but increases the solubility of a gas in a liquid.
increases the solubility of a solid in a liquid but decreases the solubility of a gas in a liquid.
increases the solubility of both a solid and a gas in a liquid
decreases the solubility of both a solid and a gas in a liquid
Spiegazione
-The solubility of gases in liquids decreases with increasing temperature. Conversely, adding heat to the solution provides thermal energy that overcomes the attractive forces between the gas and the solvent molecules, thereby decreasing the solubility of the gas
-The solubility of most solid or liquid solutes increases with increasing temperature
-The solubility of most solid or liquid solutes increases with increasing temperature
