A substance has a density of 0.85 g/cm³ and is placed in water (1 g/cm³). What will happen to it, and how would you express this using relative density?
💡 Hint: Use the formula: Relative Density = 0.85 g/cm³ / 1 g/cm³.
Explain why materials with a density of 8 g/cm³ would pose problems for construction materials used in boats.
💡 Hint: Refer back to the principle of buoyancy and sinking.
