This is the reason why metals feel colder than wood despite them being at the same temperature.
What is the metal is a better thermal conductor than the wood.
This is the reason why an inflated balloon will appear to be less inflated and start to sink towards the ground when moved from a warmer environment into a cooler environment (explanation).
As particles cool, they will slow down and condense, taking up less space and becoming more dense.
