Question 120

A scientist is studying three different polymer materials to determine their suitability for flotation separation. The density of Polymer P is 940 kg m-3, the density of Polymer Q is 1010 kg m-3, and the density of Polymer R is 1150 kg m-3. These materials are placed into a tank containing a salt solution with a density of 1025 kg m-3. Which of the materials will float to the surface of the salt solution?

A

P and Q only

B

P only

C

Q and R only

D

R only
