Density Of Balloon Essay

DENSITY is a physical property of matter, as each element and compound has a unique density connected with it. Density defined in a qualitative manner as the measure of the relative "heaviness" of objects with a constant volume. For gases the density may amount with the number of gas molecules in a constant volume.

Helium balloon: Compare the behavior of helium filled balloon with that of an air filled balloon. Even taking into account the weight of the rubber balloon, the helium balloon floats on the air and is less dense than the air. The air filled balloon sinks because the weight of the rubber balloon makes is a bit heavier and far denser. Hydrogen balloon: Compare the densities of hydrogen, helium, and air to estimate what will happen to a hydrogen balloon. In the hydrogen balloon demonstration usually not enough hydrogen fills the balloon to conquer the weight of the balloon. Sometimes you can almost see

As air is heated, it becomes less dense than the surrounding cooler air. The less dense hot air has enough lifting power to cause the balloon to float and rise into the air.
• Cold Water Vapor: What causes a cloud to sink to the earth surface and we call it fog. Tiny droplets of water are present in clouds and fog. If the surrounding warm air is cooled it sinks since it is denser, and at the same time the water as a gas is condensed into tiny droplets of water.
Application: Liquid Nitrogen Demonstration the white fog coming from the liquid nitrogen container is having the same effect as described above.

Mathematical Definition of Density
The formal definition of density is mass per unit volume. Usually the density is expressed in grams per mL or cc. Mathematically a "per" statement is translated as a division. cc is a cubic centimeter and is equal to a mL Therefore, Density = Mass = g/mL Volume
