Explanation:
a.) When you set the water container above the oil container and remove the card, the water sinks and the oil floats. They trade places! Oil floats on the surface because water is heavier than oil. (Scientists would say that water is denser than oil.)
b.) Soda water, like other carbonated beverages, contains carbon dioxide that has dissolved under pressure. ... If the soda is left open, additional carbon dioxide will slowly escape into the air. Under warm conditions, the carbon dioxide leaves the solution faster.
