Question
Chapter 10, Problem 10.23CP
Interpretation Introduction
(a)
Interpretation:
The level of mercury on decreasing the temperature from
Concept introduction:
The change in temperature with change in pressure can be represented as follows:
Here, P is pressure, T is temperature and 1 and 2 is initial and final values.
Interpretation Introduction
(b)
Interpretation:
The approximate level of the mercury needs to be determined for the given conditions.
Concept introduction:
The manometric unit of presusre is mm Hg. It is defined as extra pressure that is generated by the column of mercury wich is 1 mm high and it is equal to 133.322 pascals. It is not the SI unit of pressure. The reading from a mercury column can be converted into other units of pressure by multiplying the height difference between two mercury levels by denisty of the mercury and gravitational acceleration.
Interpretation Introduction
(c)
Interpretation:
The approximate level of the mercury when the stopcock in (2) drawing is opened needs to be determined.

Please note that it is correct and explains it rightly:The proportion of O, C and H in the graphite oxide is:a) Constant, for the quantities of functional groups of acids, phenols, epoxy, etc. its constantsb) Depending on the preparation method, as much oxidant as the graphite is destroyed and it has less oxygenc) Depends on the structure of the graphic being processed, whether it can be more three-dimensional or with larger crystals, or with smaller crystals and more borders.
