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 everyday example of an allowance being made for a metal to expand when it is heated?
A simple everyday example is the gaps left between sections of train tracks to account for expansion due to heat. As the metal tracks heat up, they expand and can increase in length. The gaps prevent the tracks from buckling or warping by allowing them room to expand without causing damage.
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 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.
What eventually happened to the gaps left in the periodic table left by Mendeleev?
The gaps in the periodic table left by Mendeleev were eventually filled in as new elements were discovered. Scientists continued to study and experiment, leading to the discovery and verification of elements that fit into the empty spaces in the periodic table.
Why do railway tracks have gaps in them?
Railway tracks have gaps to allow for expansion when the tracks heat up. As the tracks get hotter, they expand and get slightly larger. Without the gaps, the tracks would buckle from the force of the expansion. They have fishplates located between the joins to force the rails back into lateral alignment and thus prevent derailments.In modern continuously welded rail these gaps are often cut on a diagonal to prevent this misalignment. The thermal expansion and contraction of rail track is minimal and the forces push to the outside rather than along the rail.They are also there because segments of rail have traditionally been required to be removed and replaced easily and so had to be made a manageable length.Heat expands metal, to prevent buckling in the rails the tracks are in pieces with gaps. Another reason is in case of lighting strike the electric current can only travel as far as the first gap, this preventing electrical charge getting to a train car or electrical box.because the railway lines expand during the summer and by the friction of the train with it . if the gap is not kept the rail lines would expand and break. so to avoid the breaking of the rails the gap is keptThere is gaps between railways because during summer when the sun will heat the rail which is made of iron will obviously expand.After some calculation an approximate distance is left between them.After this answer you will ask but what in winter and how does the train pass on the gaps?So this gap is nothing for the train. It is left so that during expansion when the railways will expand the rail will not change direction.For e.g:-imagine when you take 2 drinking pipe and joint them together it will change direction or even damage.when heat is supplied to a substance or material it will expand.during summer the tracks get heated as a result it will expand. if gaps are not provided, that may result in the bending of tracks.Railway tracks have expansion joints to prevent them from warping when they expand during very hot weather. The metal on railway tracks can conduct a lot of heat during sunny periods.There are small gaps between the length of the railway track because when the temperature is hot the metal will expand and cause the train to crash. So if there is a gap between the length of the train tracks the metal wont join together and cause the train to crash. When the weather is hot have you ever noticed that the trains go slower? Thats just in case the metal joins together.A.thermal conductivityB.specific heatC.thermal expansionD.thermal insulationThe gaps are there to allow for the expansion (lengthening) of the rails in hot weather. Without any gaps, the rails would buckle and go out of alignment.
