A confined quantity of air undergoes two thermodynamic processes departing from an initial equilibrium state where the temperature is 20°C, the absolute pressure is 1bar, and the volume is 0.2m3. First, the volume of the system is doubled by an isobaric process. Then, the volume is decreased back to the initial value through a process where the relation P-V1.4 is kept constant. You may assume average values for the particular heat capacities (cp and cv) to:
(a) Sketch the processes in a P-V diagram.
(b) Determine the temperature of the three states in K.
(c) Calculate the total work in kJ.
(d) Compute the total heat transfer in kJ.
Q What is Seebeck effect? Seebeck revealed that in a circuit consisting of two dissimilar metals like iron and copper an emf is developed when the junctions are maintained at
What are the advantages of fibers optics? Glass fiber optics are extremely resilient and ideally fine for working in places where the actual conductor will tend to extreme temp

A bar magnet is overhanging north end up well above a vertical coil of wire. The bar magnet is released and as it falls down toward the coil it falls along a path that will take it
How does the elevation and air pressure affect the boiling point of water? The only factor that explains the boiling point of water at any altitude is the barometric pressure (
Explain the Nuclear Notation? Chemical reactions deal with the number of electrons exchanged or shared. Nuclear reactions, on the other hand, involve protons and neutrons and
The vapour pressure of a substance at 20.0 o C is 38.1 kPa and its enthalpy of vaporisation is 49.6 kJ mol -1 . Estimate the temperature at which its vapour pressure is 80.0 k
Explain the Half-Life The decay of a nucleus is a random event. It is not possible to predict which nucleus will decay and when. Even though over a period of time, the decay
Can fiber be made any size? Well theoretically, yes. However, there are physical constraints due tothe materials and utility. Extremely large fibers have proportional bending r
