Which two surfaces would have the highest coefficient of friction?
rubber on dry concreat
What happens when you sit down on hot surfaces?
i dont know try it and see what happens
What happens to air over hot surfaces?
It moves faster and rises
If you use a hacksaw to cut a piece of metal why do they both become hot?
due to heat generated by friction of two metallic surfaces
What is used as a lubricant?
There are a couple of possible answers. Molybdenum is used to lube engine parts during rebuild as it has a lower coefficient of friction than steel. However, the person asking the question was probably thinking of carbon in the form of graphite, which is used as a general purpose dry lubricant where it's not expected that the surfaces will become too hot.
Why the tires of a car get hot when the car is driven?
The simple answer is friction. Spinning tires are coming into contact with the road. The road's surface is not perfectly smooth -- it has a certain amount of roughness so the tires can grip and propel the car forward. Any time you have friction between two surfaces, and one of those surfaces moves to overcome that friction, a certain amount of energy from the process is lost as heat.
Why does a nail head get hot when you pound it into a board with a hammer?
its called friction when you hit it with the hammer the two surfaces rub together aka the hammer head and the nail head

Why a wonder wheel which was rotating becomes hot after a sudden stop?
it becomes hot due to friction
Why does silver get hot when bent?
friction
What happens to a machine when it has too much friction?
The excess friction will cause the moving parts to heat up - even to becoming red hot! A cooling system: water, fans and radiator, or lubricating oil, is used to reduce the friction and so lessen the wear and tear on the moving parts.
Is the rubber grip of a bike handlebar high friction or low friction?
it gets hot
