the question says what is the total volume of AIR in the jar, so as air can be compressed then it should obviously contain 450cm3 and I never heard of glass being flexible in other words the 50cm3 of air in the jar is not going to disappear or fly away so ans is D
Ans 7:
Class : Class 5
The volume of the JAR is 400 cm3 . If we insert air in the jar, the VOLUME OF THE JAR will remain the same as it is mentioned that the JAR IS COMPLETELY MADE OF GLASS, which is not flexible. Therefore, the answer is C .......

I thought it would be C but after profound thinking I realised that the answer would be D
Ans 15:
Class : Class 9
It will be D as it says that the jar contains 400 cm3 air and if a 50 cm3 syring filled with air is put into the jar it will become 450 cm3 400 50 = 450 cm3.

plz dont be angry. The volume of the glass jar will not change. it will remain the same as it is not flexible. so if we compress air of 50cm3 the volume will decrease. But air occupies the available space. So, the correct answer is C.
Ans 29:
Class : Class 6
As air can be compressed and takes up the volume of container, its final volume in the jar will be 400 cm3.
Ans 30:
Class : Class 9
Correct answer is C because air can be compressed. You don't need to add 400 and 50 because air can be compressed
Ans 33:
Class : Class 8
It was forced out of the tank so it went out and the thing is 50cm³ so 400-50 50=400So the answer is 400cm³

x is put in a vase of 30 ml water . then it becomes 50 ml . so , volume of x is 50 - 30 i.e. 20 ml . then after adding y , it becomes 75 ml . then , y is 75 - 50 i.e. 25 ml . both are less than 30 ml . so , the correct answer is C . understood ?
Ans 2:
Class : Class 10
Yajat is correct because if you read the question carefully , it is written '30 ml of watter' which means that it was already filled with 30 ml of water. now x=50-30=20cm3 and y =75 - 50 = 25 mlSo correct option is c.
