Why gaps are left in concrete slaps?
With the weather the concrete can expand or contract and the gaps in the concrete are left to allow for this expansion of contraction so the concrete doesn't crack or break.
What are the particles like in a rubber band?
the particles have large gaps in them
How is heat transferred by convection out of a house?
Air inside the house next to a heat source is heated. The warmer air is less dense than colder air so it rises and moves around in currents. The warmed air may escape through gaps in doors or open windows, or it may transfer it's heat to a wall, which may allow heat to then escape through the wall by conduction.
The perceptual tendency to fill in gaps in order to perceive disconnected parts as a whole object is called?
Closure.
Why does the size of the gaps of a railway track expand on a hot day?
The size of the gaps between railway sections decreases on a hot day. This is due to thermal expansion. Nowadays different composites are used and different methods employed when laying track so 'continuous' rails may be laid.
When temperature rises what will happen to the gaps between the concrete sections?
when the tempreture rises the gaps between the concrete pavement will expand because of the heat.
When the temperature rises what will happen to the gaps between the concrete sections?
when the tempreture rises the gaps between the concrete pavement will expand because of the heat.
Why concrete roads have gaps?
because it expands and contracts depending on the temperature..the gaps allow the concrete some space to expand so that it will not crack..
Why are there gaps in between sidewalks?
Concrete, like most materials, expands and contracts with the temperature. The gaps allow the surface to do so without cracking.
Why do concrete roads have gaps between large pieces of concrete?
As the weather varies the concrete expands and contracts. If there were no gaps the concrete would buckle and crack.
Why do roads have the gaps between the large pieces of concrete?
They are expansion gaps that allow for the expansion and contraction of the concrete.
Why gaps are left in concrete slaps?

What happens to concrete when there is no expantion gaps?
It will buckle and crack leaving high and low spots with jagged edges in the most severe cases.
Why are there gaps at regular spots in the side walk?
They're called "expansion joints". Concrete expands and contracts with temperature changes. The expansion joints allow this to happen without cracking the concrete slab.
How do concrete gaps keep the concrete from cracking during the winter?
During winter when the concrete contracts/shrinks and there is no gap, then it will crack from the surface. So gaps are left in concrete such that it can shrink to a safe limit without cracking it.
Why are there gaps between the slabs of concrete pavements?
There are 2 reasons for that. Reason one: They can be expansion joints. In the winter the pavement contracts and in the summer it expands. these joints are generally gaps that go the whole way threw the pavement. Generally these joints are filled with some sort of caulking to keep moisture from getting underneath the pavement. Reason two: They can be put there as joints for the concrete to crack. when sidewalks are made and other concrete pavements, they anticipate the concrete cracking, so they put in gaps that dont go all the way threw the depth of the concrete as a place for the concrete to crack and not be unsightly.
Why are concrete highways made in short sections with tar-filled gaps between them?
The tar gaps are where the hwy has been repaired.
