SMART NOTES

7.1 Objects or Materials which are More or Less Dense than Water
1. Some objects float while others sink when put in water.
2. An object less dense than water will float.
3. An object denser than water will sink.

Float Objects Objects
Sink that float that sink

  Leaf Marble
Wooden pencil Key

4. The density of the water increases when Egg
sugar or salt is dissolved in it. Water Salt water

5. An egg put in water will sink while an egg Layer of oil
put in salt water will float. Tap water
Condensed milk
6. This is because the water that contains salt
is more dense, thus causing the egg to float.

7. The layer of oil remains at the top because
oil is less dense than water, while condensed
milk is more dense than water and remains
at the bottom of the glass.
