High school students in a physics class are asked to measure the mass and volume of two unknown liquids. The raw data collected are summarized in the following table:

  Empty Container Mass (g) Container & Liquid Mass
(g)
Volume of Liquid (ml)
Liquid A 25.0 75.0 50
Liquid B 25.0 44.7 25
   
  Questions

 

Determine the densities of the two liquids, and identify the liquids. Also, predict if an ice cube and a cork will sink or float in the two liquids.

   
  Approach

 
  • The density of the ice cube is 900 kg/m3, and the density of the cork is 250 kg/m3.
