Can you explain by illustration how to the water changes from liquid to gas what is happening to the particles of water

As the water molecule absorbs the heat energy and gains higher and higher kinetic energy, they move rapidly and collide with each other with higher frequencies -the water temperature rises. During the phase transition, the temperature of the water does not rise further  but remain constant. This is because the energy absorbed is now channeled towards the overcoming of intermolecular forces by the molecules in the transit to the next phase (therefore the energy absorbed is used to perform work).  

yes

no

blue is scattered more than other colors because it travels as shorter, smaller waves. this is why we see a blue sky most of the time.

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
