Question

Which among the following Mill's Canons can be used to explain the cause-effect relationship in Charles law?

• A. Method of Agreement
• B. Method of Difference
• C. Method of Residues
• D. Method of Concomitant Variation

Answer 1

Answer:

D. Method of Concomitant Variation

Mill's Canons are a set of principles developed by John Stuart Mill to establish cause-and-effect relationships. In the context of Charles' Law, the Method of Concomitant Variation is the most relevant canon.

Charles' Law:

Charles' Law states that, at constant pressure, the volume of a gas is directly proportional to its temperature. Mathematically, this is expressed as:

V1 / T1 = V2 / T2

Method of Concomitant Variation:

The Method of Concomitant Variation is a canon that states:

"If two phenomena, A and B, are found to vary together in such a way that as A increases, B also increases, and as A decreases, B also decreases, then it is likely that A causes B or B causes A."

Application to Charles' Law:

In Charles' Law, as the temperature (T) increases, the volume (V) of the gas also increases. Conversely, as the temperature decreases, the volume decreases. This concomitant variation between temperature and volume suggests a cause-and-effect relationship, where changes in temperature cause changes in volume.
