A) a and b
B) a and d
C) b and c
D) c and d
Correct Answer: C
Solution :
When flask 'X' is kept in a basin containing hot water, the air inside it will expand and move into the tube to push the drop of ink towards flask 'Y'. Keeping the flask 'Y' in a basin containing ice will compress the air inside it, thus, reducing the pressure in it. This will also help the drop of ink to move towards flask 'Y'.You need to login to perform this action.
