Answer: Repeat the experiment several times with the same variable and constants.

Explanation:

The experimental procedure should be performed many times so as to determine the effect of the stain remover on mustard stain in different conditions and while using different variables such as water and type of machine used. This will tell how useful the stain remover in all conditions provided to check the accuracy of the stain remover.

pressure has little effect on the solubility of liquids and solids because they are almost incompressible. True or False

Pressure has little effect on the solubility of liquids and solids because they are almost incompressible True.

Liquids and solids show little change in solubility with changes in pressure. As expected, gases increase in solubility with increasing pressure. Henry's Law states that the solubility of a gas in a liquid is directly proportional to the pressure of that gas above the surface of the solution.

External pressure has little effect on liquid and solid solubility. In contrast, the solubility of a gas increases as the partial pressure of the gas above the solution increases.

Solubility is a measure of the concentration of dissolved gas particles in a liquid and is a function of gas pressure. Increasing the gas pressure increases the number of collisions and increases the solubility, and decreasing the pressure decreases the solubility.
