# Two balls at same temperature collide inelastically which of the following are not conserved 1) Kinetic energy 2) Velocity 3) temperature 4) momentum

a) 1,2 and 3 are correct b) 1 and 2 are correct c) 2 and 4 are correct d) 1 and 3 are correct

In a inelastic collision only momentum is conserved. Kinetic energy is not conserved Loss of heat may takes place so temperature is not conserved. Since Kinetic energy is not conserved, velocity is not conserved.
So 1, 2, 3 are correct.
Hence a is the correct answer.
