If the total energy of a gas molecule is 'x' KJ before collision then the total energy of that molecule after collision?
( Assumed that collision is perfectly elastic)

Option: 1

More than x

Option: 2

Less than x

Option: 3

Option: 4

None of these

Answers (1)

Therefore, Option (3) is correct
