A closed vessel of volume 9.6 L contains 2.0 g of water. Calculate the temperature
Interpretation:
The temperature, at which half of the water remains in the liquid phase in a closed container, is to be calculated.
Concept introduction:
The ideal gas equation is as follows:
Here,
is the pressure,
is the ideal gas constant,
is the temperature, and
is the volume.
Answer to Problem 143AP
Solution:
Explanation of Solution
Given information: Volume of the vessel is
According to the ideal gas equation;
The initial mass of water is
Convert
mass to moles by multiplying
with the conversion factor,
;
for
; and
for
in the ideal gas equation as follows:
As,
Multiply
with the conversion factor
Assume temperature equal to
or
or
Compare this with the actual vapour pressure at these temperatures, as follows:
The calculated pressure at
The temperature at which half of the water remains in the liquid phase in a closed container containing
water, is
