3. Water molecules surround the
individual Na+ ion & Cl- ion & form a
Hydration shell
Hydrogen bond
Hydrogen shell
Universal solvent
Water has low viscosity, so it can act as
good lubricant
cooling effect
aquatic life can survive under freeze lake
maintain human body temperature
What is meant by specific heat capacity
Amount of heat that a liquid must absorb for 1 g of
it to be converted from the liquid state to the gaseous state
Amount of heat that a liquid must absorb for 10 g of
it to be converted from the liquid state to the gaseous state
The amount of heat that must be absorbed or lose for 10 g of a substance to change its temperature by 1˚C.
The amount of heat that must be absorbed or lose for 1 g of a substance to change its temperature by 1˚C.
