Aflat metal washer is heated. as the washer's temperature increases, what happens to the hole in the center? a flat metal washer is heated. as the washer's temperature increases, what happens to the hole in the center? the hole in the center will remain the same size. changes in the hole cannot be determined without know the composition of the metal. the hole in the center of the washer will expand. the hole in the center of the washer will contract.

answer;

The hole in the center of the washer will expand

explanation;

A flat metal washer is heated. As the washer's temperature increases, what happens to the hole in the center? A flat metal washer is heated. As the washer's temperature increases, what happens to the hole in the center? The hole in the center will remain the same size. Changes in the hole cannot be determined without know the composition of the metal. The hole in the center of the washer will expand. The hole in the center of the washer will contract.

this is an example of area expansivity.

coefficient of area expansivity is change in area per area per degree rise in temperature

a=dA/(A*dt)

as the temperature rises , there will be volumetric and area expansivity on the body. volume also increases because of the intermolecular forces of attraction between the molecule is now getting apart.

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the

happy to
