Does concrete expand when heated?
Yes , just the same as steel - otherwise the rebar would crack structures !
What is distortion in welding?
it moves Because almost all Elements expand when heated and contract when cooled. As you are welding the metal at that location is trying to expand because of the heat. Ahead of the weld area the metal isn't moving. Behind the weld area the metal is trying to contract as it cools. If the whole weld could be heated at once it would expand then contract at the same rate without distortion.
Does gold conduct heat?
All things expand when they are heated. Gases expand the most, liquids less than gasses, and solids expand the least. Yes they do. Take metal for example it expands when it gets hot.
What is the function of the expansion tank in a hot water heating system?

What liquid expands when heated?

Why not measure amounts of liquid when hot?
Heat = expansion. The water molecules expand when heated. The container will expand, and then the measurment will be off?
Oil expand or contract when heated?
Oil does expand when heated and contracts when cooled.
Will two objects of the same material expand by the same amount when heated if one is twice as long as the other?
They will expand by the same percentage, but that percentage, of course, results in more actual length of expansion on the longer object.
Why does water grow when heated?
water grows when heated because the molecles vibrate more due to the transition of energy from the heat to the water, thus causing them to expand aka grow.
Does gas turn to water when heated?
If a hydro-carbon is burnt it will make heat, CO2 and water however if a hydro-carbon is heated it will just expand into its surroundings
