When you heat a metal ring does the hole become larger or smaller?

It expands; example/ If you take a bearing for a ( motor shaft-not an engine, an electric MOTOR ) to install a new bearing after removing the others simple heat the new one to a moderate temperature with gloved hands slide it onto the shaft. It cools rapidly and is on the shaft as though it was pressed on.

Is a good heat conductor a metal or nonmetal?
Metal
Does metal conduct heat readily?
Metal does indeed conduct heat readily. Metal also conducts electricity. The conductive properties of metal are due to the free electrons in metal atoms that allow for mobile charge.
Why is it safer to use a nonmetal spoon when cooking something on the stove?
It is safer to use...say a wooden spoon instead of a metal spoon because metal is a heat conductor...or when metal touches heat the heat goes through the metal (it does the same with electricity). There is a simple answer for it!
What does heat do to metal?
When heat is applied to metal: It expands the metal Makes it hotter (Obviously) Makes it more maliable (Bendy) Can change its state to liquid at extreme temperatures.
Why is a base of a scaucepan made of metal?
It is made of metal because metal is the best conductor of heat.
Do bigger planet become geologically dead sooner than small planets?
No. Smaller planets become geologically dead sooner. A larger planet has a larger volume and thus a larger heat reservoir than a smaller planet and so can remain geologically active for longer.
Why does a metal spoon kept in hot tea become hot?
The heat will transfer to the spoon (if metal).
Will soap become larger when heat is attracted?
Yes, because the chemicals in the soap react with the heat in a chemical raction. When the heat attracts to the soap the soap will inflate and become bubbles.
If you heat a piece of metal with a hole in the center how will the size of the hole change?
It would get larger due to the expansion of the metal (see the related links)
When heat energy causes an object to become larger what happens to the object?
It expands
Why are many of the tundra mammals larger than the mammals in the tropics?
They need more heat for there bodies if they were smaller they wouldn't be able to make as much heat
Do arctic foxes keep warm or cool?
They have smaller ears to conserve heat. Foxes from warmer areas have larger ears to help dissipate heat.
Why do large organisms live in cold climates but small organisms can't?
Larger organisms are required to consume and give off lots energy to survive. But, smaller organisms do not consume and release as much energy than larger ones. This energy, when given off, is represented by heat. Therefore, larger organisms produce more heat than smaller organisms, and this extra heat is required in cold climates.
Does the size of ice affect its melting time?
Because the larger the piece of ice is, the longer it will take for heat to melt it. I smaller piece of ice has fewer layers that heat needs to penetrate to melt it compare to a larger piece of ice.
When a piece of metal with a capacity inside is heated will the hole gets larger or smaller?
When you heat a metal all of the atoms try to get further apart including those on the inside edge of the capacity. The only way to do this is by increasing the size of the capacity. You can see this in action if you've ever got a glass stuck inside another. The best way to separate them is to heat them up in hot water so that the outer glass expands. Not sure what "with capacity inside" means. When you heat a piece of metal with a hole in it, the hole gets bigger. Imagine a sheet of metal with a circle drawn on it. Heat it up. Everything expands, Including the circle. The same is true if you actually remove the metal from inside the hole.
Why does the electric wire become loose in summers?
The metal wires expand in the heat - making them sag.
When a metal rod is heated at one end why does the other end become hot?
# Hot. # Longer. # Larger diameter. # More resistive to current flow. # The speed of sound in the metal increases. # Its strength decreases.
