When is resistance desirable?
resistance is useful when a plane is flying in the air, air resistance. it is also useful when a boat is floating on water, water resistance.
What is the difference between roof water resistance and waterproof asphalt felt?
Roof water resistance is your roof's resistance to rain where waterproof asphalt felt is the actual waterproof material.
What should be the insulation resistance in a electrical circuit?
As we know thath insulators are the materials which are mainly use to insulate any conducting body from the LIVE supply whether 3Ph or single phase, so the reristence of such an insulator should be infinity as it should be provide maximum resistance to the flow of current through it.
How the thickness of transmission lines reduce resistance?
The electrons in a wire travel mostly along the outside of the wire and hence the bigger the circumference the more surface area decreasing the resistance. An analogy is a vat of water with a valve at the bottom. Imagine that the water is a store of electrons creating a potential or voltage. If you only open the valve a little, the water will flow out of the vat slowly and hence the higher the resistance. As you open the valve further there is less resistance and more water can flow.
Why is your cold tap water misty?
Cold tap water is not itself misty. Rather, the cold temperature condenses water vapour in the air onto a conducting surface, such as a glass, a pipe, or a porcelain toilet tank.
What is the major factor affecting the amount of water vapour?
The major factor affecting the amount of water vapour is temperature.
What 4 things can you find at home that is diffusion?
ice turns to water waters turns to water vapour and then vapour is turned into water again
Why is diffusion of water vapour not an example of osmosis?
Osmosis is the movement of water molecules but water must also be in the liquid state and move across a semi-permeable membrane. Water as water vapour acts like a gas so this cannot be called osmosis.
What has the author Walter Althof written?
Walter Althof has written: 'The diffusion of water vapour in humid air into adhesive layer of bonded metal joints ='
What does water condenses into?
Water evaporates into water vapour, and water vapour condenses into water.
Is water heated from water vapour?
NO. Water vapour is created by heating water e.g. when you heat a kettle steam floats out of the top of the kettle, that's water vapour.
What is water turned into gas called?
It is called water vapour or simply vapour.
Is water vapour in the liquid state?
yes, water vapour is in a liquid state
what is the molecular mass of water vapour?
The molecular mass of water vapour is 18.01528
What does water vapour do?
Water Vapour is a colourless, odourless gas which is made of tiny water droplets.
what does water vapour?
Water Vapour is a colourless, odourless gas which is made of tiny water droplets.
Why can you see clouds but not water vapour in the air?
It is because water vapour is air so it can't be seen but when we breath out in the mirror,water vapour is found.
