Can we distinguish between the nternal energy of a body acquired by heat transfer or work done by external agent?

Distinguish between heat and work, and justify the statement that heat and work are interrelated.

A battery is used to charge a parallel plate capacitor till the potential differece between the plates becomes equal to the electromotive force of the battery. The ratio of the energy stored in the capacitor and the work done by the battery will be

A Carnot heat engine working between 27^@ C and 127@ C takes up 800 J of heat from the reservoir in one cycle.The work done by engine is :

In a process , 701 j of heat is absorbed by a system and 394 j of work is done by the system. What is the change in internal energy for the proces ?

In deriving Bernoulli's equation, we equated the work done on the fluid in the tube to its change in the potential and kinetic energy. Do the dissipative forces become more important asthe fluid velocity increases ? Discuss qualitatively.

Consier a Carnot's cycle operating between T_1 = 500 K and T_2 = 300 K producing 1 k J of mechanical work per cycle. Find the heat transferred to the engine by the reservoirs.

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?
