Question

A. Give reasons. 1. Why do ice cubes always float at the top of a glass of water?

2. Why are liquids denser than gases?
3. Why do icebergs float in ocean?
4. A cork floats in water while a solid ball made of the same material sinks.

Only correct will get the tag of brainliest.​

Answer 1

Answer:

1. Believe it or not, ice is actually about 9% less dense than water. Since the water is heavier, it displaces the lighter ice, causing the ice to float to the top.
2. Density: The molecules of a liquid are packed relatively close together. Consequently, liquids are much denser than gases. ... Because of their higher kinetic energy compared to the molecules in a solid, however, the molecules in a liquid move rapidly with respect to one another
3. Density =mass/volume and solid balls are more dense (have more mass per volume) than water so they sink due to gravity. ... Cork is lighter than an equal volume of water, so it floats
