Maria and Jane set up a lemonade stand one summer to earn money for a trip to the beach. They noticed that the hotter the day, t

he more glasses of lemonade they sold. They mixed up the lemonade exactly the same way every day: the same amount of sugar, lemon juice, and water. They added ice to the glass when they poured the drink. They always used the same size glass. They decided to chart their sales in order to figure out how much lemonade to make each day, using the weather forecast as their guide. Identify the independent, dependent, and controlled variables in the girls' experimental data.

Independent variable: weather condition

dependent variable: sales of lemonade drink

controlled variable: the lemonade drink mixture.

Explanation:

From the description of the problem, the independent variable is the weather condition whereas the sales of lemonade drink is the dependent variable.

A dependent variable is one in which relies on the outcome of another variable. The independent variable does not rely on other variable. It is usually the cause in an experiment.

  • The weather condition is an independent variable. Maria and Jane are simply trying to project their sales(dependent variable) on the condition of the weather.
  • A control is that variable that does not have effect on the experiment. It is usually not the subject of an investigation and has no effect on the outcome. The Lemonade mix of lemon, sugar and water has no effect.

The volume of a fixed mass of a liquid sample increases as the temperature rises from 20 to 40˚c. does the density increase, dec
Mandarinka [93]
Density is the ratio of the substance's mass to volume. To know the effects of temperature on the density of the liquid, we must look at the mass and volume dependence. Mass is always constant, so it is not affected by temperature. For volume, generally, the molecules of the liquid occupy a greater space when heated because of the rapid collisions of the liquid molecules. Thus, as temperature increases, the volume of liquid also increases, although slightly only. That means that density would decrease.
