Would the cap of a plastic bottle sink or float on water? Answer: The cap of plastic bottle floats when put in the water since it is plastic.

## Do bottle caps float?

According to Eriksen (2005), the densities of these plastic materials (see Table 2) are all less than the density of ocean water, which means things like grocery store bags and plastic water bottle caps should float on the top of the ocean.

## Why do plastic caps float on water?

Plastic has a certain density, so not all plastic floats on the ocean surface. If the density is greater than that of sea water, the plastic will sink, and the plastic floats if it is less dense than water.

## Have you seen that some things float on water while others sink Think how this happens?

Think how this happens? Answer: Yes, I have observed that certain things float on water while others sink. Everything displaces water equal to its volume. If the displaced water is more than the weight of a thing, then the thing floats, otherwise it sinks in water.

## Why do things sink and float in water?

Objects that are more dense than water sink and those less dense float. … When an object floats, it pushes water out of the way ( displacement ).

## What density does something have to be to float in water?

LESS than 1 g/cm3, it will FLOAT in water.

## What sinks slowly in water?

Potatoes sink in water. Any object that is denser than water displaces less volume of water than its own weight. This causes a resultant force downwards where weight is greater than upthrust so the object sinks.

## Could you see the salt after it dissolved in water?
