At 340.0k the average Kinetic energy is 4.24014 kj/mol.
An object's kinetic energy is the energy it has as a result of motion. Applying force is necessary if we want to accelerate an object. We have to put in work to apply a force. After the work is finished, the object will be moving at a new, constant speed because energy has been transferred to it.
At 170.0k the average kinetic kinetic energy of helium gas is 2.12007 kj/mol.
