Question

You transfer a one liter of lemonade into a 2-liter size pitcher, and the lemonade fills up half the container. Does the density of the lemonade change? Next you transfer a liter of oxygen into a 2-liter size container, and the gas expands to fill the entire container. Does the density of the oxygen change? Finally, you take a ball of clay and flatten it out like a pancake. Does the density of the clay change? Explain your answers. How could you perform an experiment to see if your answers are correct?

Answer 1

1. Density of lemonade does not change as we fill it into container, as lemonade does not fill the whole pitcher. So, the volume of the lemonade does not change and so the density also does not change.

2. Now if we transfer oxygen into container, its volumes is changed as the gas fills up the whole pitcher and expands, so its density also changes.

3.The clay is also almost incompressible, so when we compress it, its shape changes and its volume remains the same, so its density also remains the same.
