Question

Liquid is filled in a flask up to a certain point at room temperature. When the flask is heated, the level of the liquid

• A. Immediately starts increasing
• B. Initially falls and then rises
• C. Rises abruptly
• D. Falls abruptly

Answer 1

The correct option is B Initially falls and then rises

Both the liquid and the flask undergoes volume expansion on heating. The flask expands first and hence the level of the liquid initially falls and after sometime liquid expands, due to which there is a rise in the level of liquid.
