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.
(i) These are positive ions having similar mass if the experimental gas does not have isotopes. However if the gas has substances then positive pulses are group of positive ions ha
The microwave (rotational) spectrum of 12 C 16 O having a series of lines spaced by 115.3 GHz. Suppose that the rotational energy levels of this molecule can be approximated by
a) Spin motion of electrons b) On the basis of spin and orbital motion of electrons c) These are feebly attracted in an external magnetic field i.e., have a tendency to go fr
In certain ranges of a piano keyboard, more than one string is tuned to the same note to provide extra loudness. For example, the note at 110 Hz has two strings at this frequency.
