Considering a system consisting of an ideal gas, can you please briefly describe each of the following:

A	adiabatic expansion
B	isothermal compression
C	isothermal expansion
D	adiabatic compression

Expert Solution

A) An adiabatic process is one in which no heat is gained or lost by the system. It means Q = 0 and it means change in internal energy is equal to the work.

In adiabatic process we have

PV = constant

where is adiabatic constant.

---------------------------------------------------------------------------------------------

B) Firstly, Isothermal means constant temperature. If dQ amount of heat is transferred to the surrounding at temperature T of surrounding as well as system(for isothermal process)

entropy change of universe = entropy change of system+ entropy change of surrounding

entropy change of universe = 0 (here, heat leaves the system)

----------------------------------------------------------------------------------------------------------------------

C) In isothermal expansion, heat is added to the system. Here, heat enters the system.

same definition as (b)

--------------------------------------------------------------------------------------------------------------------------

(d) . In adiabatic compression, volume decreases, pressure increases. This is due to the reason that work energy is converted to internal energy which in turn increases temperature.

An ideal classical gas can be defined as one gas with a fixed number of particles at a fixed temperature which satisfies the following conditions: 1. the internal energy does not depend on the volume 2. the enthalpy does not depend on the pressure Use this definition to derive the equation of state pV = N kT by employing appropriate thermodynamic potentials and exploiting Maxwell relations.

To derive the ideal-gas equation, we assume that the volume of the gas atoms/molecules can be neglected. Given the atomic radius of krypton, 1.1 Å, and knowing that a sphere has a volume of 4πr3/3, calculate the fraction of space that Kr atoms occupy in a sample of krypton at STP. Express your answer using two significant figures.
