Warm air is less dense than cold air. pressure. and are spread farther apart. Therefore there are fewer air molecules in a given area to push down on you.

Why is warm air lighter than cold air short answer?

Warm air is lighter than cold air because they have more heat energy, which results in the increase in distances between the molecules. This decraeses the density, and hence makes it lighter than cold air.

Which is lighter heat or cold?

What’s worse dry heat or humidity?

To keep cool, humans shed excess heat through sweat, which evaporates into the air. High humidity prevents sweat from evaporating as readily, making humid heat more dangerous than dry heat.

Is humid air good for lungs?
