Why is atmospheric pressure greatest at sea level?
Why is atmospheric pressure greatest at sea level? Most gas molecules in the atmosphere are pulled close to Earth’s surface by gravity, so gas particles are denser near the surface. With greater depth of the atmosphere, more air is pressing down from above. Therefore, air pressure is greatest at sea level and falls with increasing […]
Does buoyant force depends on density?
Does buoyant force depends on density? According to Archimedes principle, the buoyant force of a partially immersed body is equal to the weight of the displaced liquid. Therefore the buoyant force depends upon the density of the fluid and the submerged volume of the body. Does buoyant force depends on density of object? Notice how […]

What is photosynthesis formula?
What is photosynthesis formula? The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products. What […]

What happens to electrons in an ionic compound?
What happens to electrons in an ionic compound? Ionic compounds are formed as the result of the formation of positive and negative ions. Electrons are actually transferred from one atom to another to form rare gas electron structures for each ion. The atom which forms a positive ion loses electrons to the atom which gains […]
