Does temperature affect odor

Answer 1

Yes temperature affects odour.

You can only smell gasses, or particles held in the air which you can inhale.

At higher temperatures materials will find it easier to transfer to a gaseous state, or to break down into small enough particles to be carried by wind.

At very low temperatures when objects will freeze they become virtually odourless as the solid material can not reach your nose.

If we use the wonderful dog poo analogy.

On a hot day the smell will travel faster, further and smell worse than on a cold day as it will break down, and particles can be carried by higher energy warmer air.

A frozen poo is near odourless.

Answer 2

Yes, temperature can affect the intensity and perception of odor. Higher temperatures can increase the volatility of odor molecules, making them more likely to evaporate and be perceived as stronger. Similarly, lower temperatures can decrease the volatility of odor molecules, resulting in weaker odor perception.
