What independent variable mean?
When conducting scientific experiments, the researcher manipulates an "independent variable" (i.e., some physical parameter that can be controlled) in order to measure the effects of such manipulation on a "dependent variable" (i.e., the results of changing the physical parameter of interest). For example, one could lower the temperature in a refrigerator (the temperature being an independent variable) and wait to observe when water left in the refrigerator turns to ice (the change from liquid water to the solid form being the dependent variable). Thus, the change in the dependent variable depends on the manipulation of the independent variable. The independent variable is the variable you change, the dependant variable is what changes as a result of what you change.
Is flour dissolving in water a physical or chemical change?
It is a physical change because it is still there and in the same form, just smaller. YOu can separate it from water if you want to which makes it physical.
How do you change from standard form to slope intercept?
Solve the standard form for the dependent variable, commonly 'y'.
What is The thing you change in an experiment?
The chemical composition and physical state of substances can change during an experiment.For example two reactants in solid or liquid form can react in an experiment to give a product in a gaseous form.
What is the noun form of variable?
The word 'variable' is both an adjective and a noun.The noun 'variable' is a word for something inconsistent or able to change; a word for a thing.The noun forms of the adjective 'variable' are variableness and variability.

What makes water vapor form?
heat
When a cube of ice melts to form a puddle of water a physical or chemical change?
When a cube of ice melts to form water, it undergoes a physical change. This is because the substance remains water in both states, but changes from a solid form (ice) to a liquid form (water) due to a change in temperature.
What is the form that makes up water?
The chemical formula of water is H2O.
How do you change the word poppies in to singular form?
Change the IES to Y and that makes poppy.
When water changes to steam it undergoes a chemical change true or false?
False. When water changes to steam, it undergoes a physical change, not a chemical change. Heating water to its boiling point causes it to change from a liquid to a gas, but the chemical composition of water (H2O) remains the same.
What ways might a microwave oven change the state of water?
The microwave oven can change water's solid form (ice) to liquid. It can also change water's liquid form into that of a gas (steam).
