Water Flashcards
Main properties of water (9)
1- polar molecule
2- solvent
3- reactive
4- metabolite
5- high specific heat capacity
6- high latent heat of vaporisation
7- strong cohesive properties (between water molecules)
8- cohesion
9- colourless with high transmission
Polar molecule
Acts as a solvent
Solvent
Metabolic reactions can happen faster in solution
Reactive
Takes place in condensation and hydrolysis reactions
Metabolite
Water molecules can also be involved in chemical reactions directly
High specific heat capacity
Water in and around our cells absorb heat energy without temperature increasing too much- buffers changes in temp
Strong cohesive properties
Can be pulled through plants in column as the water molecules held together by h bonds
Cohesion
Produces surface tension supporting small organisms
Colourless with high transmission
Light can pass through cells for photosynthesis
What is an ion
When atoms gain or lose electrons
Positively or negatively charged
