Question

The answer given is (4).

I totally understand that it is trying to test  “air can be compressed to a certain extent.” 
 
But is (4) correct answer?

The 130cm3 of air after being compressed into container A or B, its volume changes to 100cm3 in container A or 120cm3 in container B.  

The container can only contain a fixed maximum volume of air as the container is solid and it has definite volume.  i.e  Container A wont be able to contain 130cm3 of air, but up to 100cm3 of compressed air or normal air.
 
Answer shall be (1).
 
Your view?
 
 

Answer

I actually agree with your point. 

 

So I went to ask my daughter about this question. Her answer is (4).

Reasoning: 

If you have 130 cm3 of air now, which container can contain this amount of air ?

The answer is all – because it will just be compressed into the smaller containers.

 I guess I shall not be thinking too much about this question, shall just think like primary school student and provide the answer teacher wants 🙂

If the question is phrased like what Zappy has suggested – ‘If you have 130 cm3 of air now, which container can contain this amount of air ?” I will choose (4) with no doubt.

The correct answer is (4)

Because air can be compressed.

What you mentioned is right where the container is fixed as the containers have definite volume and definite shape. 
As for air, it has no definite volume and no definite shape.

Meaning to say, even if you transfer 1000cm3 into all containers, all the containers can still contain it. 
OR
if you transfer 50cm3, the containers will have 100cm3, 120cm3 and 150cm3 respectively.
