समान ताप पर दो गेंदें टकराती हैं। क्या संर

 When two balls at the same temprature collide, some fraction of their $K E$ appears in other forms of energy, like heat energy, second energy. Hence neither temparture, nor velocity or $K E$ will remain conserved. The only quantity which will remain conserved. The only quantity which will remain conserved. The only quantity which will remain conserved is their momentum.
