Answer :
Explanation : In the molecule of the hydrogen bonding forces tend to resist any phase transition form liquid state to gaseous phase, and these hydrogen bonding forces are greater usually when the hydrogen is bound to an electronegative atom like chlorine, fluorine,oxygen,etc. This then lowers the viscosity of the compound.
A.movement and protection
Answer:
the wrong statement is
d) the order of conductivity for different states is gas > liquid > solid
Explanation:
- the correct order is solid > liquid > gas
the thermal conductivity is a property of materials that it values the ability to transmit heat through them. In general, for metals and solid of continuos bodies the conductivity is high.
k = q / ΔT
∴ q: heat flux
∴ ΔT; temperature gradient
When a material undergoes changes of states, the thermal conductivity can change. for example, the conductivity of frozen water (a 0°C) is higer than that of liquid water.....from literature.
Answer:
B = b -a/RT
C = b^2
a = 1.263 atm*L^2/mol^2
b = 0.03464 L/mol
Explanation:
In the given question, we need to express the van der Waals equation of state as a virial expansion in powers of 1/Vm and obtain expressions for B and C in terms of the parameters a and b. Therefore:
Using the van deer Waals equation of state:
With further simplification, we have:
Then, we have:
Therefore,
Using the expansion:
Therefore,
Thus:
equation (1)
Using the virial equation of state:
Thus:
equation (2)
Comparing equations (1) and (2), we have:
B = b -a/RT
C = b^2
Using the measurements on argon gave B = −21.7 cm3 mol−1 and C = 1200 cm6 mol−2 for the virial coefficients at 273 K.
[/tex] = 0.03464 L/mol
a = (b-B)*RT = (34.64+21.7)*(1L/1000cm^3)*(0.0821)*(273) = 1.263 atm*L^2/mol^2
