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

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
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 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।
Sir aap bahut acha padhate ho hum numerical se darte th par aap wo dar mera khatam kar diye thanku sir you are my best teacher of science

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.

धातू गरम होणे के बाद फैलता (प्रसरण होता है) है

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

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

Railway track ki gap thermal expansion ke wajay se rahte hai
Dear sir dil se dhanayabaad sir
The rails expand on account of thermal expansion due to increased temperature in summer
By liener expansion
Thanks sir ji aap ne aaj se chemistry shuru kar di
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
Best teaching..
Nice teaching sir ji...
गर्मियों के दिन में टेंपरेचर बढ़ने पर एक्सपेंशन होता है जिसके वजह से railway track के बीच में गैप रखा जाता है

Nice season sir
Good job sir thank you
Bilkul sir
Very nice sir
Thank you sir ji
hamesha ki tarah best session tha
Due to thermal expa.
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
Bahut achha class sir
Nice class sir and thanku so much sir

Jb rail niklti h to plriyan garm hoke failti h ... Isiliy gap hota h
Your teaching is too much helpful,thanku sir
Modern physices बचा huaa hai गुरु जी
Dil le liya chemistry ne to sir bass ap ese hi sath dete raho sir
Sir lakdi bhi to solid hai ese garm karne par ye to liquid me nahi badalta hai
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।
