Question

Which among the following Mill's canons can be used to explain the cause-effect relationship in Charle's 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

• Method of Concomitant Variation: This canon states that if a phenomenon varies in any quantitative manner whenever another phenomenon varies in a particular manner, it is linked by a cause-and-effect relationship.

• Application to Charles's Law: Charles's Law describes a relationship where as the temperature ($T$) of a gas changes, its volume ($V$) changes in a corresponding, continuous, and proportional manner.

• Because both variables fluctuate together quantitatively, this relationship is best explained using the method of concomitant variation.
