Question

As pressure on a gas is increased the volume of the gas decreases. Is that theory, law, or hypothesis?

Answer 1

Is a theory. See the explanation below, please.

Step-by-step explanation:

This phenomenon is explained by the Boyle-Mariotte Law, where as the pressure of a gas increases, the volume decreases and vice versa, all at a constant temperature (they are inversely proportional magnitudes). This law is explained by the following formula:

Initial P x Initial V = P Final x Final V
