Explain the following statement you feel cooler on a hot day when you turn on a fan even though the air being blown around is hot?

Before you turn on a fan, the air is essentially hot because it is still and there is no circulation byconvection of the air currents. When you turn on the fan, it sparks a circulation where the hot air at the top flows to the opposite side of the room, and then eventually becomes cooler and more dense, falls to the floor, and is pushed back towards the fan by the incoming hot air. So, when you turn on the air, the fan is just cirulating hot air, not making it colder. The air only becomes cooler when it flows away from the fan.

Can energy pass to a hotter subject to a cooler object?
There's no scientific reason why heat energy can't flow from a cooler objectto a warmer object, making the cool one cooler and the warm one warmer.But the probability of it is so small that the statement "That never happens." isused in the field of Thermodynamics as if the statement were a law of nature.
Explain whether your body gains or loses thermal energy if your body temperature is 37 C and the temperature around you is 25 C?
Heat flows from a hotter body to a cooler one, and never the reverse.
Why do hot air balloons rise with hot air?
Hot air is less dense than cooler air, therefore the balloon will rise (float) on the cooler air around it.
How do you keep something hot in a cooler?

Can you use the process of convection to explain why it is cooler in the shade?
I honestly tried finding a way for my homework, and apparently we couldn't think of anyway that CONVECTION can explain why it is cooler in the shade. The best way you can try is RADIATION :D If you want to do something with CONVECTION , you can say something about like a liquid such as tea in a shade, becoming the same level as its environment. that's what i read ALLL over the internet.... i no i didnt help, but yea :D
