Two ball at the same temperature collide which is consved?

Options

A. Temperature
B. velocity
C. kinetic energy
D. Momentum

Answer

D

Explanation

When two balls at the same temprature collide, some fraction of their `KE` appears in other forms of energy, like heat energy , second energy. Hence neither temparture, nor velocity or `KE` 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.
