The given question provided the data of an experiment to determine the effect of water temperature on the amount of sugar that dissolves in a beaker of water and asked to identify the components:
- Amount of Water (mL) - constant
- The temperature of Amount of Sugar - constant
- The Temperature of water (°C) - variable
- Amount of Sugar dissolved (g) - variable
In any research investigation or experiment, there are three main parts that are:
- Independent variable: These are the variables that are manipulated or change to see the effect on the dependent variable, these are manipulated by the researcher. In this investigation, the independent variable is the temperature of the water as it affects the amount of sugar that dissolves.
- Dependent variables: these are the variable that also changes due to change and according to the change in the independent variables. In this investigation, the amount of sugar that dissolves changes according to the change in the temperature of the water, thus, its dependent variable.
- Constant or control: these are the parts that do not change during the experiment so there is no other influence occur in the Dependent variable.
Thus, the correct answer is -
- Amount of Water (mL) - constant
- The temperature of Amount of Sugar - constant
- The Temperature of water (°C) - variable
- Amount of Sugar dissolved (g) - variable
