The reason electric fans work to cool a person is not by cooling air. Heat radiates out of human beings through skin cells. (When a person is hot the process of getting rid of the excess heat is speeded by perspiration which evaporates. When the air is humid as well as hot the extra moisture in the air slows down evaporation. This is why people feel so much hotter in a humid environment at a given temperature than they do in a less humid one at the same temperature.) Fanning pushes the heated air surrounding a person away from the skin so that the person feels, and is, cooler.
So, keeping a fan on in a room which contains nothing which is alive is a waste of energy.
So if I put about a cup of Epsom salts and some bubble bath in my tub and soak for at least five minutes (in hot water) I am not going to get clean? I use soap on my underarms, feet, etc. and use shampoo on my hair but I do not soap my entire body. Now you have me wondering just how clean I am!Soap works to clean due to its unique molecular structure. When someone is "dirty" it means that dust and other environmental substances have mixed with oils which stick to the skin. Water alone can't wash it off because oil and water don't mix - the water simply rolls off. The reason oil and water don't mix is because oil molecules are non-polar - they have no electrical charge - while water molecules are polar - one end carries a positive charge, the other a negative one. Water molecules are consequently magnetically attracted to charged molecules, including each other, and not attracted to non-polar molecules.
A soap molecule is engineered with two parts rendering it somewhat a snakelike; the body of the snake is a lengthy non-polar structure, and the head an attached polar structure. The two can exist together because the attachment, a glycerol molecule, has both polar and non-polar properties. The dual electrical nature of the soap molecule - the non-polar body, and the polar head - allow it to mix with both water and oil.
What happens is when soapy water is applied to dirty skin the attraction the water molecules have toward one another force them under and around the oil molecules, surrounding and isolating them into microscopic globules. The oil molecules can mix with the water since it contains soap which has non-polar properties as well as polar, so the oil is lifted away from the skin, and with more water applied washes the dirty solution away.
I'm reading up on your question, Neese. I suggest you read what I'm reading as well, in order for you to best get your answer...So if I put about a cup of Epsom salts and some bubble bath in my tub and soak for at least five minutes (in hot water) I am not going to get clean?

p.s. I have a very deep tub too!
Just think of all the bacon and ice cream you could eat!!!Riot, I hope today is more cheerful for you
Someone who weighs 155 pounds on Earth would only weigh 25.7 pounds on the Moon. I'm going to go live on the moon lol.
