The internal energy of a system depend on what ?

The internal energy of a system remains constant when it undergoes (i) a cyclic process (ii) an isothermal process (iii) an adiabatic process (iv) any process in which the heat given out by the system equal to the work done on the system

The internal energy of a system during isothermal process decreases.

What is the internal energy of a system ?

Explain the internal energy of a system.

A thermodynamic system is taken from an initial state I with internal energy U_i=-100J to the final state f along two different paths iaf and ibf, as schematically shown in the figure. The work done by the system along the pat af, ib and bf are W_(af)=200J, W_(ib)=50J and W_(bf)=100J respectively. The heat supplied to the system along the path iaf, ib and bf are Q_(iaf), Q_(ib),Q_(bf) respectively. If the internal energy of the system in the state b is U_b=200J and Q_(iaf)=500J , The ratio (Q_(bf))/(Q_(ib)) is

For increase in internal energy of a system is equal to the work done on the system. Which process does the system undergo ?

With what the internal energy of real gases be determined ?

Assertion:- Net work done by all the internal force of a system is independent of choice of reference frame.

The potential energy of a system increase if work is done ……….
