Conductivity,<span>the degree to which a specified material conducts electricity, calculated as the ratio of the current density in the material to the electric field that causes the flow of current. It is the reciprocal of the resistivity.</span>
Answer:
ΔS = 7.618 J/K
Explanation:
The entropy change associated to an isothermal process is:
ΔS =
We can calculate Q (heat) how:
Q = nRTln()
Where Vf = 2.5v
Vi = v
R = 8.314J/mol.k (Constant of ideal gases)
n: Number of moles = 1 mol
Then
Q = nRTln(2.5)
ΔS =
ΔS = (1)(8.314)ln(2.5)
ΔS = 7.618 J/K
The electric current should also double. :)
Answer:
109.779BTU/lbm and 220.179BTU/lbm
Explanation:
We have the values of Pressure and Temperature,
At the tables, this conditions are for enthalpy and specific energy,
We calculate now the heat transfer for the system,
We can calculate now the work transfer given by,
