The long distance yoyage of plastic

 I read an article called The Long Distance Voyage of Plastic. This is an article about plastic which is thrown in the sea. Scientists have been collecting these plastic particles from the sea for 20 years.It's weird that they are collecting the same quantity of plastic these days as they used to collect 20 years ago, although much more plastic objects, such as bottles and bags, are consumed now. Scientists don't know where this plastic disappears. It may sink down to the bottom of the ocean or marine life eats it .

 My first reaction to this  article was anger, why do people throw plastic in the sea?! Why don't they recycle it? Plastic is bad for sea-creatures because they can be harmed by floating plastic objects. They can eat plastic, which is poisonous. Plastic is also bad for the sea itself because it gets dirty and it is a type of the worst pollution.
I hope someday  people will stop throwing plastic and other bad materials into the sea.

The States of Matter

                                   

state	mass	shape	volume	expanding on heating	compressi- bility	example
solid	definite	definite	definite	real low	no	rock, wood and glass
liquid	definite	indefinite	definite	slightly	low	water, milk and gasoline
gas	definite	indefinite	indefinite	large	easy	oxygen,hydrogen and carbon dioxide

                              







 The patterns I noticed:

• All three states have a definite mass
• Gas is least definite because it has indefinite shape and volume and it is easily compressed
• Expanding on heating and compressibility increase from solid to gas
• Solid state has all physical properties definite
