Question

the metastable curve represents______of supercooled water. volume density mass vapor pressure

Explanation:

In thermodynamics, for supercooled water (water below its normal freezing point but still in liquid state), the metastable curve on a phase - diagram represents the vapor pressure. Volume, density, and mass are not typically represented by a metastable curve in this context. Vapor pressure is a key property related to phase - behavior and the metastable state of supercooled water.

Answer:

vapor pressure
