D

## Ans 4:

Class : Class 4
d won't be the correct answer. the answer is c as air can be compressed.

Class : Class 6
C

## Ans 6:

Class : Class 5
Correct answer is C because air can be compressed. You don't need to add 400 and 50 because air can be compressed

## Ans 7:

Class : Class 5
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 8:

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 14:

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 .......

hello

## Ans 16:

Class : Class 5
air can be compressed and it would be 450 cm3 answer is d

Class : Class 5

Class : Class 7
d

## Ans 19:

Class : Class 5
I thought it would be C but after profound thinking I realised that the answer would be D

Class : Class 5
Class : easy

## Ans 21:

Class : Class 4
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

Class : Class 4
ans is D

Class : Class 6

## Ans 24:

Class : Class 7
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.

Class : Class 7
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 8:

Class : Class 5
B is 25ml which is less than 30 ml ... B is the answer

## Ans 9:

Class : Class 6
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.

Class : Class 5

## Ans 11:

Class : Class 5
Both B and C are right so please donÃ¢Â€Â™t quarrel

## Ans 12:

Class : Class 6
option c is wrong only y has 25ml volume and x has 50ml , z also has 50 ml of volume so , option b is correct

Class : Class 7

## Ans 14:

Class : Class 4
When Y is put it looks like it rose from 50 to 70.

## Ans 15:

Class : Class 5
ANSWER is c as many people don't see that the container already had 30 ml of water
