Explain why the fusion curve of ice has a negative slope whereas the sublimation curve has a positive slope in the phase diagram of water
Answers
Explanation:
In water's diagram, the slope of the line between the solid and liquid states is negative rather than positive. The reason is that water is an unusual substance in that its solid state is less dense than the liquid state. Ice floats in liquid water.
Answer:
The fusion curve of ice has a negative slope since the density of water increases, whereas the sublimation curve has a positive slope since the density of water decreases.
Explanation:
When the temperature of water boom from 0 Celsius to about four Celsius, molar quantity decreases, the density of water boom. That is why the slope of the fusion curve of water has a poor pitch.
Whereas at some stage in sublimation, as temperature increases, the molar quantity will increase, meaning the density of water decreases. That is why the slope of sublimation is positive.
