FAQ
Q: What is density?
A: Density is a measure of how much mass is contained in a given volume of a substance.
Q: How is density calculated?
A: Density is calculated by dividing the mass of an object by its volume.
Q: What is relative density?
A: Relative density compares the density of a substance to the density of another substance, typically water.
Q: How is relative density calculated?
A: Relative density is calculated by dividing the density of the substance by the density of water.
Q: What is hydrostatic pressure?
A: Hydrostatic pressure is the pressure exerted by a fluid at equilibrium due to the force of gravity.
Q: How is hydrostatic pressure calculated?
A: Hydrostatic pressure is calculated by multiplying the density of the fluid by the acceleration due to gravity and the depth of the fluid.
Q: What is atmospheric pressure?
A: Atmospheric pressure is the pressure exerted by the weight of the atmosphere above a particular point on Earth.
Q: How does pressure change with depth in a fluid?
A: Pressure increases with depth in a fluid due to the increasing weight of the fluid above pushing down.
