The initial conditions for an air-standard Otto cycle operating with a compression ratio of 8:1 are 95 kPa and 17o C. At the beginning of the compression stroke, the cylinder volume is 2.20 L ( 1 L=0.001 m3)and 3.60 kJ of heat is added during the constant volume heating process. Calculate the pressure and temperature at end of each process of the cycle, and determine the thermal efficiency and mean effective pressure of the cycle.
Planck radiation law A law that defined blackbody radiation better than its predecessor, therefore resolving the ultraviolet catastrophe. It is depend on the supposition that e
KINEMATICS II 1. The concept of the derivative of the function is exceptionally important. The derivative shows that how fast the function changes when its argument is changed.
When a certain beam of light falls upon a metal surface, it ejects photoelectrons from it. The number of photoelectrons ejected per second by the beam of light depends upon on
Sound waves are being used to determine the depth of a freshwater lake, as shown in the figure below. If the water is 25°C and it takes 1.2 s for the echo to return to the sens

If a force applied on a body causes a alteration in the normal positions of the molecules of the body, resulting in a alteration in the configuration of the object either in length
Define isothermal process For isothermal process temperature remains constant i.e. Δu = 0. Thus according to first law of thermodynamics ΔQ =Δw Heat supplied to the syste

kelvin; K (after Lord Kelvin, 1824-1907): The basic SI unit of thermodynamic temperature explained as 1/273.16 of the thermodynamic temperature of the triple point of water.
Explain the Photoelectric Effect Atomic Models Heinrich Hertz first observed the photoelectric effect in 1887. He noticed that if a photon with enough energy is absorbed by an
