Give one example each for solid,liquid,and gas showing expansion with an increase in temperature and contraction with a decrease in temperature.

(N/A) For Solids: $A$ metallic lid on a glass jar that is stuck can be opened by placing it in hot water. The heat causes the metallic lid to expand more than the glass,loosening it for easy removal.
For Liquids: The mercury in a clinical thermometer rises when placed in warm water due to thermal expansion. When the thermometer is removed and cooled,the mercury level falls due to contraction.
For Gases: $A$ partially inflated balloon placed in warm water will expand as the air inside gains kinetic energy and occupies more volume. Conversely,a fully inflated balloon placed in cold water will shrink as the air inside contracts.
