Fill in the blanks for these statements:
1. The volume of a submerged body is equal to the ___________ of the fluid displaced.
2. The weight of a floating body is equal to the ____________ of the fluid displaced.
3. Why is it easier to float in saltwater than in freshwater?
1. Volume.
2. Weight.
3. When you’re floating, the weight of water you displace equals your weight. Saltwater is denser, so you don’t “sink” as far to displace your weight. You’d float even higher in mercury (density 13.6 g/cm^3 ), and you’d sink completely in alcohol (density 0.8 g/cm^3 ).
