The difference in density between gases creates buoyancy, which is the ability of an object to float. at 0°c, helium has a density of 0.18kg/m 3. at 0°c, regular air has a density of 1.29 kg/m 3. in kilograms, how much mass can a cubic meter of helium float in regular air at 0°c?

Explanation:

The buoyant force in kilograms is given by

state the principle of separating two immiscible liquids by separating funnel. describe an activity with diagram to separate a mixture of water and kerosene oil. answer: immiscible layers separate out in layers depending on their densities in separating funne
