Question

expulsion of smoke while talking during cold climate​

Answer 1

Here is your answer dear✌

When you exhale when it's cold outside, the water vapor in your breath condenses into lots of tiny droplets of liquid water and ice (solid water) that you can see in the air as a cloud, similar to fog. ... As temperatures drop, it's more likely that you'll be able to see your breath.

Hope it helps you dear✌✌❤.
