Choose the statement which is not correct
(a) Water shows anomalous expansion by expanding if it is cooled below a certain temperature
(b) Many objects such as rail tracks , road joints are specially designed to allow extra spaces for thermal expansion
(c) A beaker is completely filled with water at 40C. It will overflow both when heated or cooled
(d) A brass disc is just fitted in a hole in a steel plate .The coefficient of thermal expansion of brass is more than the coefficient of thermal expansion of steel The system must be heated to loosen the disc from the hole.

Answer:
(c) A beaker is completely filled with water at 40C. It will overflow both when heated or cooled
Answer:
At 40C, a beaker is totally filled with water. When heated or chilled, it will overflow.
Explanation:
What is meant by thermal expansion?
In most cases, phase transitions are not included in thermal expansion, which is the tendency of matter to change its form, area, volume, and density in response to a change in temperature. A substance's average molecular kinetic energy determines temperature in a monotonic manner.
The tendency of matter to modify its form, volume, and surface area in reaction to a change in temperature is known as thermal expansion. A substance's average molecular kinetic energy determines temperature in a monotonic manner.
Gases expand as temperature rises, which is the basic premise of thermal expansion. The size of a balloon will increase if its contents are heated.
Therefore, the correct answer is option (c) A beaker is completely filled with water at 40C. It will overflow both when heated or cooled.
