Gases are a unique state of matter because the volume of a gas can be compressed or expanded based on its temperature. Jacque Ch
arles studied these changes by observing hot air balloons. For a given mass, as the gas is heated its volume expands and as it cools the volume contracts. Charles found that the volume is directly proportional to temperature when the mass and pressure remain constant. Which equation represents the relationship in Charles' law?
Since Charles found that the volume is directly proportional to temperature when the mass and pressure remain constant this means that with increase in temperature, there will be increase in volume.
Mathematically, at constant Pressure
This equation represents the relationship in Charles' law.
Equation representing the relationship in Charles' Law;
V α T ; where; V is the volume of a gas, while T is the temperature in Kelvin
Thus; V/T = Constant.
<h3><u>Explanation</u>;</h3>
According to Charles' Law; when the temperature of a gas is increased at a constant pressure, its volume increases, and when the temperature of a gas is decreased at a constant pressure, its volume decreases.
Therefore; <em><u>the volume of a fixed gas is directly proportional to absolute temperature at constant pressure</u></em>. That is; V α T (in kelvin)
The ICD-10-CM that should be reported is the O10.013. This is for pregnancies with pre-existing hypertension complicating the pregnancy in the third trimester. Since the patient is predisposed to pre-eclampsia from previous pregnancy and she is in her third trimester, the code to be used is O10.013.
