does boiling water run faster than cold water or does cold water run faster ?

Answer 1

The viscosity of water reduces with higher temperatures, it becomes more "fluid". Hence given the same pressure difference as colder water, the hot water will flow more easily (faster).

It is to do with energy, but nothing to do with the kinetic energy of the mass of flowing water.

It relates to the inter-molecular bods beteewn the water molecules. these bonds become overcome as the energy (heat) is put into the water.

Answer 2

As the visocity of water increases with increasing temperature the hot water would be slightly faster, as it would flow a little more easily. But also with cold water being slightly denser would this travel slightly faster with the same forces and pressure exerted behind?

Hot water would travel faster but this would only be measurable with water at the boiling point if it is measureable! But probably isnt. There are also a number of other factors to maintain in such an experiment assuming the water is absolutely pure and the two taps are brand new and perfect copies of each other:

Temp (have to be taken at a range of temps), Pressure, Dissolved Oxygen content, <- I think thats it?

Answer 3

I think the bubbles in boiling water reduce the apparent surface friction between the water and the substrate and results in faster flow. But I can't say from personal observation.

Answer 4

Common sense would suggest that boiling water may have lower viscosity than cold water (just as hot oil is thinner than cold oil). Whether the difference would be measurable is another matter.

Answer 5

personally iw ould say cold water would run faster than boiling water, but it could also come down to the pressure behind the water

Answer 6

yes boiling water vil run faster den cold water , this is bcoz hot water molecules have greater kinetic energy this is due to their higher temperature . thus hot water molecules shud flow faster

Answer 7

Hot water runs faster because it has more kinetic energy, and therefore, its molecules flow faster out of the faucet.

Answer 8

The viscosity of water does decrease with increasing temperature - see Web article cited below. So other things being equal, yes.

Answer 9

Lets put them in a 100 metres race to decide.

Answer 10

Neither as the viscosity of water doesn't change.
