Float or sink?
2 likes9,521 views
This document discusses why regular cola cans sink while zero cola cans float in water. It explains that an object will float if it has a lower density than the liquid, and sink if it has a higher density. The density of a substance is its mass divided by its volume. It provides a formula for calculating density and lists the materials needed for an experiment to measure the mass, volume, and density of regular and zero cola cans to determine why they behave differently in water.

- 4. FLOAT OR SINK? An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in. The density of a substance is its mass per unit volume. Formula : d = m / V Unit : kg/m3 Water density = 1000 kg/m3

- 8. FLOAT OR SINK? Calculate the volume by submerging it in water : 1. Fill up the graduated beaker about half way with water. 2. Write down the measurement 3. Submerge the object 4. Take the new measurement. 5. Subtract the new measurement from the original. The difference, is the volume of the object.
