Type of graph, name of the independent variable and dependent variable when glass of water is set in direct sunlight for 2 hours and when its temperature is measured in every 10 minutes.
Explanation of Solution
Introduction:
A variable is a quantity whose value can be changed.
Now in any experiment if the value of one quantity is systemically changed in order to measure its effect on another quantity, then the quantity which was chosen by the experimenter to change is called the independent variable.
And the other quantity whose value changes due to the change of the value of independent variable is called the dependent variable.
You would use to display your data by using a line graph. This is the best option for this experiment. Because the line graph clearly shows how the dependent variable changes due to change in the independent variable. They are often used when the variable changes with time.
Here temperature is the dependent variable and time is the independent variable.
Conclusion:
Often the values of independent variable and dependent variable will be plotted on graph to deduce the relationship between them and as a result prediction can be tested and made.
