Question

Three identically shaped deflated balloons are attached to the mouth of three empty glass tubes, I, II and III. Each test tube is placed inside a glass tumbler containing water. All the three glass tumblers contain the same amount of water that has been heated to attain different temperatures of T₁, T₂ and T₃respectively.

The temperature is the highest in test tube II and the lowest in test tube III. The temperature in test tube I is in between II and III.

After some time, changes were observed in the volume of air inside the balloons.

Solution

The correct option is C
II is larger in comparison to the volume of air inside balloon I

When the test tubes attached with deflated balloons are placed in different glass tumblers containing water heated to different temperatures, the air present inside the test tube is heated by the temperature of the water in which the test tube is placed.

Warm air expands and causes the balloon to inflate, thereby increasing the volume of air inside the balloon.

The extent of inflation depends upon the temperature of water. Maximum expansion is observed in the balloon attached to the tube placed in water that has the highest temperature.

The temperature of test tube II is the highest. Therefore, the volume of air inside the balloon attached to this test tube will be the maximum.

The temperature is least in test tube III. Therefore, the volume of air inside the balloon attached to this test tube will be the minimum.

The temperature in test tube I is between that of test tubes II and III. Thus, the volume of air inside the balloon attached to test tube I is less compared to the balloon attached to II and greater in comparison to the balloon attached to test tube III.

The correct answer is C
