Why gaps left between two sections of rail tracks?
Metal can expand slightly when heated by the sun, a small gap allows the rail to expand, that said modern rail tracks are welded and do not have these gaps.
What is the function of the gaps at the railway?
It depends which gaps you mean! Older track was laid in discrete sections with gaps left between them to allow for expansion on hot days. There are gaps between rails at the points which are used to connect different tracks together in turn. Is this what you mean?
What is the purpose of the gaps in train tracks?
Expanding on other previous answers:Tracks have gap because metal needs space to expand and contract. In summer the tracks tend to expand (heat leads to expansion). And in winter, tracks tend to contract.If no gaps were left than the two bars of metal will fight to expand and lead to cracks in the rail. This is the same reason why you see perfectly spaced cracks or divisions in sidewalks, bridges, parking garages, and buildings.Ultimately, tracks have gap for safe expansion of the metal.Read more: Why_do_tracks_have_gaps
What eventually happened to the gaps left in the periodic table left by Mendeleev?
he knew that later on the gaps would eventually get filled up
What does it mean when the elephant is laying on its left side?
It is not laying on its right side!
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.
Which are the nouns in The rabbit left tracks in the snow in your yard?
rabbit, tracks, snow, yard
Why was leaving spaces and gaps in the periodic table later vindicated?
Those gaps were later filled by elements discovered after the creation of the table, which justified the gaps being left for that purpose.
When Mendeleev changed the lay out there were gaps how did the gaps help scientists looking for undiscovered element?
When he left gaps because he needed to let some of the air in for he can get all of the piese together.
What is a sentence for pitiless?

What did homesteaders do to stop fires?
Some left gaps in their crops.
What was Mendeleev able to do with the gaps he left in the periodic table?
Mendeleev left those gaps for the elements which were not discovered at that time. He named those elements like eka-aluminium,eka -silicon etc.
