The first law of thermodynamics for a closed system is dU = dq + dw, where dw = dw_(pv)+dw_("non-pv") . The most common type of w_("non-pv") is electrical work. As per IUPAC convention work done on the system is positive. A system generates 50 J electrical energy, has 150 J of pressure-volume work done on it by the surroundings while releasing 300 J of heat energy. What is the change in the internal energy of the sytem?

Does the internal energy of an ideal gas change in an adiable process?

Two cylinders A and B of equal capacity are connected to each other via a stopcock. A contains a gas at standard temperature and pressure. B is completely evacuated. The entire system is thermally insulated. The stopcock is suddenly opened. Answer the following : What is the change in internal energy of the gas ?

For the real gases reaction, 2CO(g)+O_(2)(g)to2CO_(2)(g),DeltaH=-560 kJ. In 10 litre rigid vessel at 500 K the initial pressure is 70 bar and after the reaction it becomes 40 bar. The change in internal energy is :

Does the internal energy of an ideal gas change in an isothermal process

Assertion :- Internal energy of a real gas may change during expansion at const. temperature. Reason :- Internal energy of a real gas ia function of T & P .

A gas expands against a variable pressure given by P = (20)/(V) (where P in atm and V in L). During expansion from volume of 1 litre to 10 litre, the gas undergoes a change in internal energy of 400 J. How much heat is absorbed by the gas during expansion?
