1.Liquids can flow because their particles can move over each other. When water is poured into a glass, the particles of water move over each other and into the corners of the glass. The particles keep on moving over each other as the water takes the shape of the glass. The animation shows how this works.
2. The latent heat absorbed by ice is greater than the heat absorbed at water at the same temperature. Thus, ice appear cold to mouth than water.
3.when you use a cold compress, you are utilizing heat loss via conduction. it's getting rid of the high temperature caused by the fever by transfering coldness to the individual and absorbing some of the heat to the compress.
