a student wanted to investigate whether or not the temperature of the water would affect the solubility of sugar she had three glasses of water each with 200 ml of water in them one was at 10 c the second a 25c and the third one was at 40 c she found that the warmer water dissolve more sugar what are the dependent and independent variables.
I dont understand if you can just point me in the right direction and not give me the whole answer but just help me with the variables that would be nice.

Of course! I'll guide you in identifying the dependent and independent variables in this experiment.
The independent variable is the factor that the researcher intentionally changes or manipulates. In this case, the independent variable is the temperature of the water. The researcher has three different temperatures of water: 10°C, 25°C, and 40°C. By varying the temperature, the researcher is trying to determine its effect on the solubility of sugar.
The dependent variable is the outcome or response that the researcher measures or observes. It depends on the independent variable and is expected to change as a result of its manipulation. In this experiment, the dependent variable is the solubility of sugar. The researcher is observing how much sugar dissolves in each glass of water at different temperatures (10°C, 25°C, and 40°C).
So, in summary:
- Independent variable: Temperature of the water (10°C, 25°C, 40°C)
- Dependent variable: Solubility of sugar
By comparing the solubility of sugar in the three different temperatures of water, the student can draw conclusions about how temperature affects the solubility of sugar.
is the water temperature dependent on the amount of sugar
or
is the amount of sugar dissolved dependent on the water temperature
can you change the water temperature by dissolving more or less sugar
or
can you change the amount of sugar dissolved by changing the water temperature
what depends on what?
