3. When applied to materials, what does 'density' refer to?

   1. Mass per unit volume
   2. Ability to bounce back
   3. Ability to change shape
   4. Hardness
   Show answer

   Answer: A. Mass per unit volume

   Density refers to the ratio of mass to volume and helps in categorizing materials based on how closely their particles are packed.

4. Which material would be best for making a frying pan?

   1. Glass
