Because the water dissociation is an endothermic reaction.
Because the water dissociation is an endothermic reaction.
The ionic product constant of water, Kw, is temperature dependent because the dissociation of water into hydronium ions (H3O+) and hydroxide ions (OH-) is an endothermic reaction. As temperature increases, more water molecules dissociate into ions, leading to an increase in the concentration of H3O+ and OH- ions, thus affecting the value of Kw.
The quantity of salt added to water is under your control and it will change the boiling point of water,i,e. the temperature of water. So quantity of salt is an independent variable while the temperature of water is dependent variable, when other factors are kept constant.
temperature of water. :) and youre welcome(:
A dependent variable depends on the independent variable. If you are doing an experiment about how temperature affects the heat of water then the independent variable would be the temperature, as that is what you are going to change, and the dependent variable the water as the temperature of the water depends on the temperature surrounding it.

You can keep water heated to a constant temperature by using a water heater with a thermostat that monitors and regulates the temperature. Insulating the water tank can also help maintain heat. Additionally, using a recirculating pump or a tankless water heater can help ensure a constant supply of hot water.
When water is boiling, the temperature remains constant, as the energy it is absorbing is being used to change the liquid water into water vapor.
It is dependent on the environmental water temperature.
yes
If the amount of water vapor in the air does not change, the relative humidity will remain at 80% as long as the temperature remains constant at 75°F. If the temperature changes, the relative humidity will change, as it is dependent on both temperature and the amount of water vapor in the air.
To maintain constant the temperature if necessary.
