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
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
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
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

गर्मी के दिनों में तापमान बढ़ने पर रेल की पटरियों में थोड़ा सा फैलाव आ जाता है इसलिए पटरियों में थोड़ा अंतर रखा जाता है।

ट्रेन High speed चल ने के बाद में पट्री गरम हो जाती है sir
धातू गरम होणे के बाद फैलता (प्रसरण होता है) है
इसी लिये छोटासा गॅप रखा जाता हैl
You are super star Sir. Answer of Hw- Garmi me track ki lambai bad jati hai issliye track ke bich me gap rakha jata hai.

Thermal expansion k baje se rails ki size thodi si increase hoti hai. Uske baje se rails me gap rakhte hai

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.

H.W .... धातु गर्म करने पर फैलती है और ठंड में सिकुड़ती है
क्योंकि ठोस ऊष्मा पाकर फैलता है इसीलिए लोहे के दो पटरियों के बीच खाली स्थान छोड़ा जाता है।

गर्मियों के समय मे तापमान अधिक होने पर रेल पट्टियों कुछ फैलाव आता है जिस वजह से इसमें अंतर रखना आवश्यक होता हैं

Sir lajawab class as always
Sir train k track pe gap isliye hota h kyoki iron grami me flta h to isliye jgh chohdi jati h taki uska flne k. Liye jgh mile
The rails expand on account of thermal expansion due to increased temperature in summer

गर्मियों के दिन में टेंपरेचर बढ़ने पर एक्सपेंशन होता है जिसके वजह से railway track के बीच में गैप रखा जाता है
Your teaching is too much helpful,thanku sir
Excellent sir
In railway track gap is provide because the metal expands on heating or shrinks when it cools.
Sir summer season me ye lohe hot hoker fail jate hain
To good 👍👍👍👍👍👍👍
Thermal expansion

रेल की पटरियां लौहे की बनी होती है जो कि गर्मी के दिनों में फैलता हैं। gap इसलिये छोड़ी जाती है ताकि पटरी फैल कर टेड़ी ना हो जाए।
