## What will happen to the object if its density is lesser than that of the fluid?

The density of an object determines whether it will float or sink in another substance. 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.

## What happens to objects with a greater density than water?

The density of an object can change if either the mass or volume of the object is changed. Fluids, such as water, have a certain density. If an object is more dense than water, it will sink; if it is less dense than water, it will float.

What happens when water is less dense?

In practical terms, density is the weight of a substance for a specific volume. The density of water is roughly 1 gram per milliliter but, this changes with temperature or if there are substances dissolved in it. Ice is less dense than liquid water which is why your ice cubes float in your glass.

### Why does ice sink in rubbing alcohol?

The ice cube sank in the rubbing alcohol, because rubbing alcohol is less dense compared to ice.

### Which do you think is denser less dense can you tell why?

Answer: Students should realize that if an object weighs more than an equal volume of water, it is more dense and will sink, and if it weighs less than an equal volume of water, it is less dense and will float.

Does ice float on vodka?

The molecular structure of liquid alcohol is very different than that of liquid water and more complex. In particular, the spacing between molecules in liquid alcohol is larger per unit volume than that of ice. For this reason, the ice cube will sink at the bottom of a glass of alcohol.

#### Can iron float seawater?

Because denser fluids have more weight for same volume displaced, so greater buoyant force. Hence, easier to float in ocean’s seawater than freshwater pool (recall earlier). And, iron floats in mercury but sinks in water…

#### What happens if an object is less dense than water?

If the object is less dense than water, the water will be able to keep it afloat. If the object is more dense than water, the water will not be able to keep it afloat, and it will sink. How can you determine whether solid object is more dense or less dense than water?

Why do objects float in water while others sink?

The density of water is 1 g/cm cubed, and objects more dense that water will sink, while objects less dense than water will float. An object will sink if it weighs more than the water it pushes away, and an object will float if it weighs less than the water it pushes away.

## Why is a ship less dense than water?

Because of its curved hollow design, whenever a ship sinks into the water it’s not just bringing steel below sea level, but it’s also bringing all this air, which ends up making the total ship seem a lot less dense than just the material it’s made out of.
