in the diagram below, particles of the substance are moving from the liquid phase to the gas phase at the same rate as they move from the gas phase to the liquid phase.\nthe gas and liquid are at\n- equilibrium.\n- a high vapor pressure.\n- a low vapor pressure.
Answer
Brief Explanations:
When particles of a substance move from the liquid phase to the gas phase at the same rate as they move from the gas phase to the liquid phase, this is the definition of phase - equilibrium. Vapor pressure is related to the tendency of a substance to vaporize, but the key here is the equal - rate movement indicating equilibrium.
Answer:
equilibrium.
