It varies. A saturated solution of NaCl in water increases the boiling point, higher than 100oC. I suppose most impurities increase the boiling point.
yes
Depending on what is in it, the boiling point will either rise or fall.
Yes, impurities have important effects on the melting and boiling point of materials.
Let's say substance A is the substance and substance B is the impurity. The boiling point of the mixture would be somewhere between that of A and B, depending on the amount of impurities in the mixture.
Impurities can lower the melting point and raise the boiling point of a pure substance. This occurs because impurities disrupt the crystal lattice structure of the substance, making it harder for the molecules to align and transition between solid and liquid states. The presence of impurities can also alter the intermolecular forces between molecules, affecting the energy required for melting and boiling.
i have worked with my students and found water to boil at 97 degrees Celsius.this water had carbonated and bicarbonates as it was ordinary water.
Impurities in a substance can raise or lower its boiling point, depending on the nature of the impurities. When impurities are added to a liquid, the boiling point of the solution increases due to the decrease in vapor pressure. This phenomenon is known as boiling point elevation. Conversely, impurities in a liquid can also lower the boiling point by disrupting the intermolecular forces between the solvent molecules, causing a decrease in boiling point, known as boiling point depression.
Boiling is used to describe a change of state of a pure liquid to vapour phase. The particular temperature at which this change of state occurs is defined as the boiling point of that specific liquid. Now the question is will addition of impurities have any effect on the boiling point of water. The addition of impurities such as salt or sugar to pure water raises its boiling point.

The freezing point of water decreases when the number of dissolved molecules (or better particles) in the solvent increases. This is called freezing point depression and you can easily find the relation between the quantity of particles dissolved and the freezing point on Wikipedia.
Effects are: boiling or thermal decompostion.
Each substance has a different effect on the boiling point.
