I am wondering if you are referring to "heat index" and "wind chill factor". These terms refer to what the temperature actually is and what it feels like.
Hot air. That's what makes it float.
Heat flow determines how hot or cold something feels when you touch it.
Air moves from hot to cold.
Hot air can hold more water vapor than cold air. As air temperature increases, its ability to hold water vapor also increases due to the increased kinetic energy of the molecules, allowing more water molecules to be suspended in the air. This is why warmer air feels more humid.
Thermal conductivity most determines how hot or cold something feels when you touch it. The nerve endings in your skin determine what is hot and cold when you touch it.
Air can vary in temperature, so it can be cold or hot depending on the environment. Cold air is denser and can feel refreshing, while hot air is lighter and can feel warmer on the skin.
Hot air rises and cold air falls.
No, hot air is less dense than cold air.
Thermal conductivity most determines how hot or cold something feels when you touch it. The nerve endings in your skin determine what is hot and cold when you touch it.
Yes, air flows from hot to cold.
Yes, hot air can hold more moisture than cold air. As temperature increases, the capacity of air to retain water vapor also increases, allowing for higher humidity levels in warmer conditions. Conversely, cold air can hold less moisture, which is why it often feels dry in winter months. Thus, while hot air may not always contain more moisture, it has a greater potential to do so compared to cold air.
A girl that feels hot to the touch can be cooled down a couple of ways. She can drink some cold water or she can take a cool bath or she can enter an area that has air conditioning.
