the temp of water
(what they changed)
Density, Melting and boiling points, shape, color, temperature and so many other physical quantities.
boiling point of a liquid is directly related with the external pressure(some times Air pressure). directly related means that increase in value of one variable(independent) results in increasing value of other variable(dependent). when the vapor pressure of the liquid becomes equal to that of external pressure,the liquid boils. The temperature at which they becomes equal is called Boiling piont of liquid.
A substance's boiling point indicates the temperature at which it transitions from a liquid to a gas. If the substance's boiling point is below room temperature, it will be a gas at room temperature. If the boiling point is above room temperature, it will be a liquid at room temperature.
This depends on the pressure.
The saturation temperature of a vapor is the temperature at which it condenses to a liquid at a given pressure. It is also known as the boiling temperature of a liquid, as it is the temperature at which the vapor pressure of the liquid equals the surrounding pressure, resulting in boiling.
The independent variable! =] the dependent variable is what is changed by the independent variable... Eg... And a bad one at that lol... But the affect of salt on the boiling point of water... Salt is independent variable... Dependent is the boiling point =]
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.
In simple distillation, the independent variable is the temperature of the heating element. By varying the temperature, you can control the phase change of the liquid mixture, allowing you to observe how different components vaporize and condense at different temperatures. This manipulation helps in effectively separating substances based on their boiling points.
an experiment to test a scientific hypothesis in which the variable component is controlled, not random, eg In an experiment that measures volume vs time to boiling, the volume, being the indirect variable, is measured.
Manipulated variables are variables that a scientist deliberately adds in to tweak the outcome of his or her experiment. For instance, a scientist may choose to add certain compounds into a pot of water to see if it may affect the boiling point.
Boiling temperature, Boiling point (though it's not a 'point': it is variable with pressure)
How does the altitude at which water is boiled affect the temperature at which it boils?
I did the experiment and the boiling point is 100 degrees Celsius, 212 degrees Fahrenheit.
The control variable for distillation is typically the temperature of the system. By controlling the temperature, you can regulate the separation of components based on their boiling points. Maintaining a constant temperature during distillation helps ensure a more efficient and precise separation process.
