As a liquid is under more and more pressure it's boiling point gets higher and higher. This is because it take more energy to move the molocules in a closed space. The opposite effect can be seen when water is placed in a vaccuum. If strong enough, the water can boil at room temperature because it's boiling point gets so low. The boiling point will increase. The reverse is also true.
The boiling point of water on top of Mt. Everest is around 70 degrees celcius because the pressure is so low.
An increase in the heating rate during distillation can lead to a higher boiling temperature of the liquid mixture. This happens because rapid heating can cause a more significant pressure buildup in the system, potentially elevating the boiling point. Additionally, faster heating may disrupt the equilibrium between the vapor and liquid phases, resulting in less efficient separation of components. Consequently, careful control of the heating rate is essential for optimal distillation performance.
a solution is formed when the contents added in a small amount - solute, is soluble in the solvent. When a solution is formed then there is a relative change in its boiling temperature , and it invariably increases. The increase in the temperature is based on the volatile behavior of the solute being added. Here both glass and clay are said to be insoluble in the given liquid. If we consider that clay settles down completely and doesn't form a colloid with the liquid then in that case. the expected boiling temperature of the liquid will not change. yet considering the given vessel in which the mixture will be boiled both glass and clay will act as an insulator which will in turn affect the heating of the vessel.
Each substance has a different effect on the boiling point.
An increase in temperature speeds up the reaction rate.
The independent variable in this experiment is the amount of table salt added to the boiling water. The effect of adding salt to the water is to raise the boiling point of the water, therefore increasing the temperature at which the water boils.
When a substance gets heated, it expands as it's volume expands because of the increase in volume of each molecule, that is because of the increase in kinetic energy of electrons due to heating effect. When water gets heated, and it's temperature reaches to it's boiling point i.e 100o , then the water at that temperature, due to extra expansion and the breakage of intra-molecular bonds the molecules are set free, leading to the formation of water vapour. When water gets to boiling point some of it turns into steam.
If the solid is insoluble, it will have little or no effect on the boiling point. If it is soluble, it will raise the boiling point.
The boiling point of the solution is lower, the boiling point is higher.
No, because heating matter does not effect the mass.

Pepper has the least effect on the temperature or reaction to boiling water ,As well pepper does not dissolve in boiling water like other grains.

When temperature increase the volume also increase; but if you think to volumetric titrations the effect is without importance.
Latent heat affects the shape of heating and cooling curves because it represents the energy required to change the state of a substance without a change in temperature. During phase transitions, such as melting or boiling, the temperature remains constant as energy is used to break intermolecular forces rather than increase the kinetic energy of the particles. This results in plateaus in the heating and cooling curves, impacting the overall shape of the curve.
Because the salt is an impurity it raises the boiling point by density differences
Each substance has a different effect on the boiling point.
In a multiple effect evaporator system, the boiling point elevation effect helps to increase the overall efficiency of the system by allowing for the use of lower temperatures in subsequent effects due to the higher boiling point of the solution in the previous effect. This results in energy savings and reduced operating costs compared to single-effect systems.
