. An ice block with a height of 2 cm, length of 2 cm, width of 5 cm, and mass of 18.4 g is dropped in water. Will it float or sink? In 3–5 sentences, show your calculations and explain how you arrived at your conclusion.(4 points) simple

Answer 1

Volume = 2 cm × 2 cm × 5 cm = 20 cm³.
Density = mass/volume = 18.4 g / 20 cm³ = 0.92 g/cm³.
Since 0.92 g/cm³ < 1 g/cm³ (water), the ice block will float.
About 92% of its volume will be submerged (mass of displaced water = 18.4 g).
