How is viscosity and density related?
Viscosity is the thickness or thiness of a fluid, Density is the space between particles.When a fluid is heated, it becomes less viscous(thinner) and the particles move far apart so it is less dense. Temprature affects density and viscosity.Something that is dense doesn't have to be viscous and vice versa.EX: Salt water is dense but not viscous.Honey is very viscous but not very dense
Why does a perspex block sink in fresh water but floats in salty water?
A perspex block sinks in fresh water because it is denser than the water. In salty water, the added salt increases the water's density, causing the perspex block to float. This is due to the principle of buoyancy, where an object will float if it is less dense than the fluid it is in.
Will ships float or sink in fresh water?
Ships will float in fresh water as long as their density is lower than that of the water they displace. This is due to Archimedes' principle, which states that the buoyant force acting on an object in a fluid is equal to the weight of the fluid displaced by the object.
Why does a block of wood float higher in saltwater than a block of wood in fresh water?
A block of wood floats higher in saltwater because saltwater is denser than fresh water, providing more buoyant force. The increased density of saltwater displaces more water, pushing the block of wood higher above the surface compared to fresh water.
If a substance is viscous is it denser than a less viscous liquid?

Why does a ball fall more slowly through viscous fluid than through water?
Viscosity is defined as a measure of the resistance to flow of a fluid. Therefor, the flow of, or the passage of an object through, a viscous fluid is resisted by the fluid.
Why is warm water more dense that fresh water?
fresh water is more dense than hot water and this is just a guess from a sixth grader SO DON'T JUDGE ME!!!!
What liquid is less viscous yet heavier than water?
Mercury is a liquid that is less viscous but heavier than water. Mercury is a dense liquid metal at room temperature, making it heavier than water, which is less viscous than water due to its lower viscosity.

Is salty water more dense that salty water?
Salt water is more dense than fresh water. A ship would float higher at sea, and lower on a fresh water inland lake.
Is chlorinated pool water more dense than fresh water?
No, chlorinated pool water is not more dense than fresh water. Both chlorinated pool water and fresh water have a density of approximately 1 g/cm3 at standard temperature and pressure.
Do you float in salt water or fresh water which on is more dense?
Salt
