Your independent variable when using water and oil is the type of liquid you choose to manipulate in your experiment. If you are testing how different conditions affect their interaction, such as temperature or mixing methods, those conditions would be considered your independent variables. The dependent variable would then be the outcome you measure, such as the degree of mixing or separation between the two liquids.
In a homemade lava lamp experiment, the independent variable is the factor that is being manipulated or changed by the researcher, such as the type or amount of ingredients used in the lava lamp. The dependent variable is the factor that is being measured or observed as a result of the changes made to the independent variable, such as the rate of bubbling or movement of the colored liquid in the lava lamp. Other controlled variables, such as room temperature, container size, and stirring technique, should also be considered to ensure the validity of the experiment.
Oil is slightly less dense than water and a litre of water weighs a kilogram. It would be less than a kilogram, but by how much depends on the type of oil.
A liter of water IS a kilogram. Since oil is lighter, it's about .625 kg
oil
In science , Dense refers to the "heavier" object . For example , You know how oil and water don't mix ? And do u notice how the oil floats to the bottom ? The reason why is because the oil has a higher density than water . It's kindof confusing , huh??
Well, it depends on your experiment. If you're adjusting the amount of cooking oil before an experiment, it's an independent variable. If you're calculating how much there is after the experiment, it would be a dependent variable.
The independent variable of a homemade lava lamp experiment could be the type or amount of oil used, the type or amount of water used, or the type or amount of effervescent tablets used. This variable is manipulated by the experimenter to observe its effect on the outcome of the lava lamp's behavior.
Water
The dependent variable in a lava lamp experiment could be the height of the separated oil and water layers, the speed of the moving bubbles, or the color intensity of the lamp's glow. It is the variable that is being measured and is expected to change in response to the independent variable being tested.
The variable in the project of what happens when oil mixes with water could be the type of oil used, the temperature of the water, the ratio of oil to water, or the presence of an emulsifier. These variables can affect the emulsification process, the formation of microemulsions or macroemulsions, and the overall stability of the mixture.
emulsifier. Also, a device that removes oil from water, or water from oil - depending upon its application.
The oil and water do not chemically react with each other, so they are considered immiscible. This means they do not form a homogeneous mixture, but rather separate into distinct layers due to the difference in their densities. The variable in this scenario would be the ability to observe the two separate layers when oil and water are mixed.
Is the paint you're using water-based or oil-based?
DEPENDS ON HOW MUCH OIL YOUR ARE USING
Using detergent and water to clean oil is a physical change because it does not alter the chemical composition of the oil. The oil is simply being physically separated and removed from the surface it was on, but it remains the same substance chemically.

You can cook an egg without using oil by boiling it in water or by baking it in the oven.
