Answer: A is condensation and B is freezing.
The process in which the gas changes to the liquid phase due to the removal of heat is known as condensation. Rains are formed in this way. The water vapour rises. As it raises above it loses heat and then cools down and condenses and comes down as rainfall.
The process in which the liquid changes to a solid on removal of heat is known as freezing. Formation of ice is an example. When the heat is removed at -4 degree Celsius the water freezes to ice.
Explanation:
Certain actions and/or their method can affect the environment, such as leaving the sink on while brushing your teeth or not turning off a light when you leave the room. I personally make decisions to prevent my association with Greenhouse gases by turning off lights when I leave a room, using minimal water, recycling, etc.
Answer:
The ice chunk will take 2.47 seconds to hit the water.
Explanation:
Height from which ice chunk fell = h = 30.0 m
Initial velocity of the ice chunk = u = 0 m/s
Time taken by ice chunk to cover 30.0 m of height = t
Acceleration due to gravity = g 
Using second equation of motion ;



The ice chunk will take 2.47 seconds to hit the water.
