गर्मी के दिन में रेल की पटरी थोड़ा बढ़ जाती है इसलिए उतना रिक्त स्थान छोड़ा जाता है कि जब बढ़े तब अपने आप को अरजेसट कर लेगा अगर नहीं छोड़ा जाता तों पटरी टेढ़ी हों जाएगी जिससे दुर्घटना हों सकता है

[@Edu.326]

tq so muchsir ji

[@GeetaAcademy12345]

क्योंकि ठोस ऊष्मा पाकर फैलता है इसीलिए लोहे के दो पटरियों के बीच खाली स्थान छोड़ा जाता है।

[@yogeshsonawane9940]

[@durgarohini1624]

Gaps which r of the order a few mm r provide to allow rooms for the rails to expand the rise in temperature of atmosphere temp as friction causes by running train all material expand when heat and cooled

In railway track gap is provide because the metal expands on heating or shrinks when it cools.

[@karansingh-tz9fx]

The rails expand on account of thermal expansion due to increased temperature in summer

[@suvankarpradhan4417]

In railway track gap is provide becaus metal is expand during rice the temperature and compress decrease the temperature. that's why when temperature is rice in railway track it will be expand and may chance to be crack. To prevent the damage of the railway track that gap is provide

[@sajjadsalim2895]

There is gap between two tracks because Of track spreading when getting temperature by rubbing of wheels specific heat is stored the energetic molecules of matter, conserved energy in track by increasing of temperature of the matter through crossing the train, apply force on each other. The action of force become spreading of the track in the direction of gap or space between two tracks. So that track could not get bend and train runs safely. And so on,space leaving between two tracks prevent accident of the train. Thank you so much sir
