Answer 2

Answer:

On heating, the vessel does not expand or contract in the experiment.

Explanation:

• The coefficient of apparent expansion and absorption is the same
• So the vessel does not expand nor contract even when heated
• The coefficient of expansion is the fractional change in area, length or volume per unit change in temperature at a given pressure
• The tendency of materials to change their physical properties like shape, area, volume, and density is thermal expansion
• There are different values of thermal coefficients of expansion corresponding to different materials

Since the coefficient of apparent expansion and absorption is the same, the coefficient of volume expansion is zero and the vessel does not expand nor contract on heating.
