Liam did an investigation to see how water temperature affects the amount of salt that will dissolve in the water. He filled 4 beakers with exactly 100 milliliters of water each. He then heated each beaker to a different temperature and tested salt solubility at each different temperature. What was Liam's independent variable?

amount of water in each beaker

the number of beakers

the amount of salt that dissolved in each beaker

the temperature of the water in each beaker

    The correct answer is the temperature of the water in each beaker.

    Explanation:

    The independent variable is understood as one that can vary from one case to another, so that the researcher can obtain different results from the dependent variable being studied.

    In this case, the dissolution of salt in water is the study variable. The temperature varies from one beaker to another, which is why it is our independent variable.

    The amount of water in each beaker is the same, the beaker number is fixed, and the amount of salt added to each beaker is the same, this is to see how much salt dissolves at different temperatures.

    Have a nice day!
