Prior Knowledge Questions
Q1.What is density?
Density is the amount of mass in a given volume of a substance (Density = Mass ÷ Volume).
Q2.What are the units for density?
Density is typically measured in g/cm³ (grams per cubic centimeter) or g/mL.
Q3.Why does ice float on water?
Ice floats because it is less dense than liquid water (ice density ≈ 0.92 g/cm³; water density = 1.0 g/cm³).
Activity A – Calculating Density
