|Fig. Joule’s apparatus|
I hope you understand the concept of Joule’s law for perfect gas, still any query write to us in comments section.
Thus, ” Specific heat of the material is quantity of heat required to raise the temperature of unit mass by 1°C or 1°K. “
(i) Work done in Isothermal Process
(ii) Slope of Adiabatic Curve is more steeper than Isothermal.
As a gas is compressible, then there is a rise in temperature without supplying any heat to the gas, then,
(ii) Adiabatic Process & its equation
(iii) Isothermal process & its equation
(ii) Specific Heat at Constant Pressure :
The unit of Specific Heat in C. G. S system is cal/gm/°C.

Now, From Ideal gas equation:
Here, Cp – Cv = R is required relation.
|Fig. 1 Shifts in absorption position and intensity|
It is an affected by which absorption maxima is shifted towards the longer wavelength.In this type of shift intensity remain constant & wavelength is increses due to which it is also known as red shift.
It is an effect in which the absorption maxima is shifted towards the shorter wavelength can be done by decresing the conjucation. Thus these type of the shift is known as Blue shift .
It is an effect in which the intensity of the absorption is an increases while wavelength is constant.
It is an effect in which the absorption is decreases while wavelength remain constant.
Nitro compounds are generally yellow in color, so it is clear
For example:- ethylene, acetylene, etc.
i.e:- Π- Π* and n- Π*.
An auxochrome can be defined as any group which does not itself act as chromophrous whose presence bring about a shift of absorption bent towards the red ends of the spectrum.
The absorption of longer wavelength is due to the combination of chromphrous and a auxochroms to which rise new chromophrous.
Auxochrome + Chromphrous = New chromophrous
For Example:- −OH− , −OR−, −NH2−, −NHR−, −NR2−, −SH−, etc.
Hope you guys understand this article further queries write to us in comments.
