temperature
the dependent variable changes with the independent variable. the independent variable only changes when changed by the experimenter. Time is usually an independent variable.
In most real life cases, limiting an experiment to only one independent variable makes the whole experiment a waste of time. More often than not there are several independent variables.
Not necessarily. It will be if it is the only independent variable in the system.
The independent variable is the variable that the scientist controls and can change in an experiment. There should be only one independent variable in an experiment; otherwise the cause-and-effect of the independent variable cannot be determined.The dependent variable is the variable that is affected by the independent variable.EXAMPLE:Students of the same age have been given different sleeping hours (the independent variable)The next day they are tested for their performance (the dependent variable).(Having students the same age is a third type of variable, called the constant variable or the control variable. It is deliberately kept the same to reduce any effects on the outcome.)

There is never "only an independent variable". Science and math are both the study of how changes in one thing cause changes in something else. If you can think of something that can change, and NOT have any effect on anything else, then it's an independent variable that can stand alone. But if it has any effect on anything else, then there is always something that depends on it, and that's a DEpendent variable.
