A ball easily moves but not a bus when we push them. why?

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.

Match each scenario to the form of energy it represents

The first law of thermodynamics states that heat added to a system is neither created nor destroyed but is as it changes into other forms of energy.
