Question

in the below mentioned phase diagram of water, the curve oc shows the effect of pressure on the melting point of ice. a true b false

Explanation:

In the phase diagram of water, the curve \(OA\) represents the equilibrium between liquid water and water vapor (vaporization curve), the curve \(OB\) represents the equilibrium between water vapor and ice (sublimation curve), and the curve \(OC\) represents the equilibrium between ice and liquid water. According to Le - Chatelier's principle, when pressure is applied to ice (which is less dense than water), the system will try to reduce the effect of pressure. Since ice has a larger volume than water (for the same mass), increasing pressure on ice will cause it to melt (to form water which has a smaller volume). The slope of the \(OC\) curve (which is negative for water) shows that as pressure increases, the melting point of ice decreases.

Answer:

a. TRUE
