Question

John wants to investigate the effect of temperature on dissolving sugar in water. What will be his dependent variable? A) temperature of the water B) volume of the solvent C) time taken for sugar to dissolve

Answer 1

The dependent variable in John's experiment on the effect of temperature on dissolving sugar in water is the time taken for sugar to dissolve.

Step-by-step explanation:

John wants to investigate the effect of temperature on dissolving sugar in water. His dependent variable is the time taken for sugar to dissolve. This is because the dependent variable is the outcome that is measured in the experiment, which, in this case, is how long it takes for sugar to dissolve at different temperatures. Temperature is the independent variable because it is what John is changing to observe how it affects the dissolution rate. The dissolution of sucrose in water serves as a classic example in chemistry of how solubility and dissolution rates are influenced by temperature, among other factors such as agitation, surface area of the solute, and saturation levels.

Answer 2

Answer: The correct option is A.

Temperature of the water

Step-by-step explanation:

This is because dependent variable is variable that cannot stand alone but depends on another. It is the effect in an experiment. It is what that is been measured or tested in an experiment. Temperature if the water is dependent variable because it's what is been tested or measured in that experiment. It depend on other variables.
