Hi All!


I have a qn from Conquer Sci assessment book Exercise65 Q2.

A syringe has 10ml air at first.After pushed the plunger in,the picture shows less than 10 ml.(picture showed in the book, before and after)
What is the true reading of the volume of air in the syringe after the plunger was pushed in?
Answer provided as 10 ml.Is that answer is correct?If yes why?

If we pushed in should be less than 10 ml as air can be compressed.

i searched in the web, the amount of gas(mass) still be the same,but volume will be reduced.

Just checking,
Is the syringe closed at the other end? if not the air will escape at the other end...

Jedamum,
Matter comes under the main topic \"Cycles\" which includes:-
1) Life Cycles of Animals
2) Life Cycles of Plants
3) The three states of Matter

My DD1 has the 1st 2 covered for this term and to be tested in the CA2 next week ...The last one will be at Term 4.
