Answer

Explanation:

Step1: Analyze volume - pressure relationship

As the graph shows, when volume (V) increases, pressure (p) decreases and vice - versa at constant temperature. This is the characteristic of an inverse relationship. Mathematically, for two variables (x) and (y), if (y=\frac{k}{x}) ((k) is a non - zero constant), they are inversely proportional. Here (V=\frac{k}{p}) (Boyle's law for an ideal gas at constant temperature).

Step2: Convert Kelvin to Celsius

The conversion formula from Kelvin ((K)) to Celsius ((C)) is (C = K - 273). Given (K = 100), then (C=100 - 273=- 173).

Answer:

  1. C. inversely proportional
  2. B. -173
