Why does air expand when its warm?
because warm molecules have more energy and movement and either rise when warm or expand if they're warm or surrounded by warmness.
Will a metal expand if it's thicker?
Yes, metal will expand when heated regardless of its thickness. Thicker pieces of metal will expand in all dimensions, but the expansion will be proportional to the increase in thickness.
Why does the Eiffel tower grow in summer?
The heat from the Sun causes the metal framework of the tower to expand slightly. The same happens to any exposed metal structure - including bridges. That's why bridges have an 'expansion gap' at each end.
Warm air in a balloon will what?
EXPAND.
Why do oven trays expand and contract?
heat makes metal expand.
What happens to metal when it is heated?
The atoms that make up the metal are loosened up by the heat, therefore causing the metal structure to become more flexible.
Why the height of the Eiffel Tower changes by 7.5cm between summer?
Metal will expand when warm in summer. So the Eiffel Tower will grow taller in summer, and become smaller in winter.
Why a tightly filled jam bottle cap can be uncapped by pouring warm water on it?
due to anamalous expansion of water
Why does your water tank make clicking noise?
it is were it turns on the heat to warm it upThe coefficient of expansion per degree per inch causes the metal to expand and contract making the sounds
Why does placing a jar under warm running water help loosen the lid?
There are two ways that putting a jar under warm water helps loosen the lid. When heated, materials expand. So the air in the jar could expand, reducing any internal suction. Secondly, the metal cap could expand so as to not have as much friction with the rest of the jar.
Why is warm water used to remove a tightly sealed metal cap from a glass bottle?
The warm water will cause the metal lid to expand if poured mainly on the lid. This expansion will often loosen the grip of the lid and it can be unscrewed. Sometimes, gently tapping the side of the lid on the floor several times, has the same affect of loosening the lid.
How can a metal bar be made to expand in all directions?
Heating the metal bar evenly will cause it to expand in all directions. This is known as isotropic expansion, where the material expands uniformly in all dimensions. Heating allows the atoms in the metal to move more freely, causing the entire metal bar to expand uniformly.
