How can the boiling point of a liquid be raised without adding soluble impurity?
The boiling point of a liquid is the temperature at which the vapor pressure of the liquid equals the atmospheric pressure, or the pressure above the liquid. So, to increase the boiling point without adding a solute, one can increase the pressure above the liquid.
What does it mean to oil out in recrystallization?
In recrystallization, "oiling out" refers to the process of adding a solvent in small amounts to dissolve a minor impurity that is not removed by filtration. The impurity will separate out as an oil layer, which can then be decanted or removed before allowing the remaining solution to undergo crystallization.
What effect does adding sugar to dish washing liquid have on the bubbles?
Adding sugar to dishwashing liquid can increase the viscosity of the solution, making the bubbles thicker and more stable. This can help the bubbles last longer and be more effective in cleaning dishes.
How does the melting behavior of lauric acid would change if an impurity was introduced in the sample?
The presence of an impurity in lauric acid would likely decrease the melting point of the sample due to impurity disrupting the crystal lattice structure, making it easier for the molecules to overcome the intermolecular forces and transition from solid to liquid. The impurity can act as a defect, which requires less energy to break the bonds holding the crystal structure together, resulting in a lower melting point.
What word describes how to make a solution less concentrated by adding a liquid?
Dilution is the process of making a solution less concentrated by adding more liquid to it.
Can you give Study of gas laws numerical equation?

Does the salt decreases the melting point of ice?
Adding of any type of impurity in water decreases its melting point. You might have studied that depression in freezing point is a "colligative" property according to which adding of any impurity to a pure liquid decreases the melting point and increases the boiling point of that liquid. So, adding of salt is not the only method of decreasing the melting point.

Adding sugar to dishwashing liquid can increase the viscosity of the solution, making the bubbles thicker and more stable. This can help the bubbles last longer and be more effective in cleaning dishes.
Is there a difference in boiling point in water and sulphur water?
Any added impurity can change the boiling point of a liquid.
What is the effect of a soluble and nonvolatile impurity on the boiling point of a liquid?
A soluble nonvolatile impurity increases the boiling point of a liquid because it disrupts the intermolecular forces between the solvent molecules, making it more difficult for the liquid to vaporize. This phenomenon is known as boiling point elevation.
Can result from adding or removing thermal energy?
A change in phase can result from adding or removing thermal energy. For example, adding heat can change a solid to a liquid or a liquid to a gas, while removing heat can change a gas to a liquid or a liquid to a solid.

What does adding water to a liquid do?
This depends on the miscibility between this liquid and water.
Does adding more liquid to a liquid make a solid dissolve faster?
No
Can a volatile impurity increase the boiling point of a substance?
No, a volatile impurity will lower the boiling point of a substance by disrupting the uniformity of the liquid phase. This causes the solution to boil at a lower temperature compared to the pure substance.
