The independent variable is "conditions that influence the rate of the melting of ice", or something perhaps worded a little better. See the link.
The variable in an experiment that is being measured or tested is usually referred to as the independent variable. In the case of testing the effect of water temperature, the independent variable would be the water temperature itself.
a dependent variable is the thing in your experiment you are testing or the thing that you are influencing. for example temperature. The independent variable changes on its on for example time. If you had a question : How long does it take for the water to reach 25c; the water temp is the dependent as you are measuring it, and the time is independent because you are not affecting it.
The dependent variable for a tornado in a bottle experiment could be the speed of the tornado rotation or the duration of the tornado formation. This variable would be affected by the independent variables being manipulated in the experiment, such as the amount of water or the speed of the vortex created.
Constants are the things that are kept the same each time one of the trials in the experiment is repeated. For example, constants could include the amount of water used, the brand of effervescent tablet used, the type of water used, and the fact that the water was not stirred. As many outside factors as possible should be kept constant in an experiment so that the researcher can be sure that any changes that occur do so because of the independent variable.
The manipulated variable in an experiment with a water rocket could be the amount of water or air pressure used to launch the rocket. This variable is intentionally changed by the experimenter to observe its effect on the rocket's performance.
An independent variable in science is the part of an experiment that you are purposely changing. For example, if you were to do an experiment on what type of water is best for plants, then the "special water", which might be salt water is the independent variable.

It can be, it depends on your experiment. Independent variables are the variables in an experiment that will not change. If you want to do an experiment that tests how something reacts with water, then starting with a clean controlled water sample for each test would be necessary and an independent variable. Conversely, if you were testing the cleanliness of multiple water sources, then the ideology of clean water would be your dependent variable, which would change upon each testing. WIth your given information I cannot say whether or not you would want water to be either a dependent or an independent variable for your experiment.

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.
The independent variable in an controlled experiment is what you are changing (for example, amount of water or sunlight a plant gets). The dependent variable changes because of the independent variable. Its the outcome of the independent variable.
In an experiment your independent variable does change to what you choose. An example would be an experiment testing to see if the amount of water in a pot effects the amount of time it takes for the water to boil. Your independent variable would be the different amounts of water used. Your dependent variable would be the time because it depends on the independent variable (the amount of water used) . Your constant would be the temperature because it is not changed throughout the experiment, and thus remains constant. This way you can isolate which changes affect which variables.
Temperature.
It depends on the context of which water is in. Water can be a dependent or independent variable depending on the experiment, and what you are trying to prove or disprove of your hypothesis, so there isn't an answer. It all depends on the context in which water is in.
In an experiment, the independent variable is altered, and the effect observed is the dependent variable, or outcome. The controlled variable is intended to be kept the same throughout the experiment so that changes in it do not affect the results.
An independent variable is the variable you can change in an experiment. On a graph, it's on the X-axis. A dependent variable is the result of changing the independent variable. It is literally dependent on it. The dependent variable goes on the Y-axis.
