In arid conditions, RWC values of less than 50% cause most plants to die

whereas values closer to 100% indicate plants are less affected by drought stress.

THERMAL PROPERTIES OF WATER

Pure water becomes a solid below 0°C and becomes a gas above 100°C at sea level.

When water contains dissolved compounds, such as salts, its freezing temperature drops below 0°C.

Dissolved compounds also raise the boiling point of water above 100°C.
