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?
