Will an ice cube float in a glass of alcohol? Why or why not?

Short Answer

Expert verified

No. The ice cube will not float in a glass of alcohol.

Step by step solution

01

Understanding the buoyant force

When a body is placed in a liquid, the weight of the body will act downwards. The liquid will exert a force on the body upwards, creating resistance to its motion. This upward force is called buoyant force.

The weight of the body depends on its density. If the body's density is greater than that of the liquid, the body will sink and vice-versa.

For example, if a stone is placed in water, the stone will sink to the bottom of the water. It happens because the stone has greater density than the water.

02

Analysis of the situation and conclusion

The ice has a density greater than the alcohol. As a result, the ice cube will not float on the alcohol but sink.
