Question

Four identical 1.0-L flasks contain the gases He,Cl 2 ,CH 4 ,and NH 3 ,each at 0°C and 1 atm pressure. -For which gas are the collisions elastic? A)He B)Cl₂ C)CH₄ D)NH₃ E)all gases the same

In ideal gas behavior, collisions between molecules are considered to be perfectly elastic, meaning that there is no net loss of kinetic energy in the system. All gases (He, Cl₂, CH₄, NH₃) under the conditions described (0°C and 1 atm pressure) are approximated by the ideal gas law, and thus their collisions are considered elastic. This is a theoretical assumption in the ideal gas model.
