Thermal Expansion part 2

Statement- 1 : Water is considered unsuitable for use in thermometers. Statement- 2 : Thermal Expansion of water is non uniform.

Two identical beakers with negligible thermal expansion are filled with water to the same level at 4^(@)C . If one says A is heated while the other says B is cooled, then:

Two identical beakers with negligible thermal expansion are filled with water to the same level at 4^(@)C . If one says A is heated while the other says B is colled, then:

Two identical beakers with negligible thermal expansion are filled with water to the same level at 4^(@)C . If one says A is heated while the other says B is cooled, then:

A metal rod of Young's modules Y and coefficient of thermal expansion alpha is held at its two ends such that its length remains constant. If its temperature is raised by t^(@)C , the linear stress developed in it is

A metal rod of Young's modulas Y and coefficient of thermal expansion alpha is held at its two ends such that its length remains invariant. If its temperature is raised by t^(@)c , then the linear stress developed in it is

Define the Thermal expansion.

Due to thermal expansion, with rise in temperature

Due to thermal expansion with rise in temperature:

Thermal expansion in gases is the ...................... (least/most).
