Two kilograms of an ideal gas with constant cp=1kJ/kgK and cv= 0.7kJ/kgK are contained in an insulated piston-cylinder device with an initial volume of 0.3m3 and a pressure of 10bar. The piston is then allowed to move until the volume quadruples.
If the process is considered reversible, determine:
a) The temperature of the final state in K.
b) The work in kJ.
If irreversibilities during the process cause the entropy to increase by 0.1kJ/K, determine:
c) The temperature of the final state in K.
d) The work in kJ.
e) Sketch the reversible and irreversible processes in a T-s diagram.
Non-Horizontally Launched Projectiles Assume a cannonball being launched at an angle from cannon atop an extremely high cliff. Suppose as well in which the cannonball does not
What do you mean by Moseley's law? Explain briefly its importance. Explain the origin of X-ray spectra. Describe continuous and characteristic x-ray spectrum.
Q. State Huygen's principle. Huygen's principle: (a) Every point on a specified wave front may be considered as a source of secondary wavelets which spread out with the sp
These are non-metallic compounds consisting of ferric oxide and one or two bivalent metal oxides such as NiO, MnO. These have resistivity of the order of 10 9 O cm, which reduces e
Q. If an object isn't moving, no external force acts on it. No it is always not true, there would be balanced forces which cancel each other out leaving no net force. Example:
When an electron makes transition from higher energy level having energy E2(n2) to a lower energy level having energy E1 (n1) then a photon of frequency v is emitted.
The phenomenon of decomposition of electrolyte solution into ions on passing the current by it is called electrolysis. Practical functions of electrolysis are Electrotyping, ext
Advantages and disadvantages of three phase system over single phase System A) In a single phase circuit the power delivered is pulsating. In three phase system the total power
In computing the electric field at a point call it point P in the first quadrant of a Cartesian coordinate system because of a continuous charge distribution from 0 to L on the x-a
