Answer: 7)
As we know that,
Compression factor (Z) = molar volume of a gas/ molar volume of an ideal gas
value of Z varies from 0 to 1
significances-
compression factor define the behavior of a gas
a) if Z = 1 i.e. ideal gas behavior
b) if Z < 1 that means a molar volume of gas, not greater then a molar volume of an ideal gas, attractive forces dominate in gas molecules and molecules are moving freely
c) Z > 1 that means a molar volume of a gas is greater than a molar volume of an ideal gas, repulsive forces dominate in gas molecules.
=> It reveals that any pure gas at the same reduced temperature, and reduced pressure, should have the same compression factor.
answer 11)
given that
mass of sample (h2o) = 125g and raise the temperature from 25 to 40 degree.
we know that,
specific heat of water (c) = 4.18 J/g.degree and
the heat absorbed by sample (q) = m*c*deltaT
m = 125g = mass of sample
So, q = 125 * 4.18 * (40 -25) (where 25 = initial temperature)
q = 7.837KJ
if initial temperature = 0 degree
then q = 25*4.18*40
q = 20.9KJ
