| Four glass bottles are kept in four vessels as shown in figure. |
|
| If a balloon is fixed on the mouth of each of the glass bottle, then the balloon will inflate in |
A) Case (i)
B) Case (ii)
C) Case (iii)
D) Case (iv)
Correct Answer: C
Solution :
When the glass bottle is put on the boiled water vessel, the air molecules start heating. The heat makes the air molecules move faster and cover more space, i.e., air expands. This increases the air pressure inside the balloon as pressure inside the balloon is lower than that inside the bottle. Thus, the air moves into the balloon and it starts inflating.
