must reach 41°F/5°C or below within an additional four hours‚ for a total cooling time of six hours. The proper way to cool hot liquids is to place them in a metal container in an ice water bath that reaches the same level as the liquid inside the container. Stir the liquid in the container frequently so that the warmer liquid at the center mixes with the cooler liquid at the outside edges of the container‚ bringing the overall temperature down more rapidly. Semisolid and solid foods should be refrigerated

I LIQUID STATE ii GASES STATE In solid molecules are very closed spaced where as liquids. The spacing b/w the different molecules is relatively large and in gases the spacing b/w molecules is still large Its means the intermolecular cohesive forces are large in solids‚ smaller in gases and extremely small in gases and on account of this fact solids posses compact and regional form‚ liquids molecules

variety of chemical and physical methods to determine molecular masses. One of these methods includes the Dumas method for determining the molecular weight of a volatile liquid. This method‚ which was proposed by John Dumas in 1826‚ makes use of a volatile liquid (vaporizes at a relatively low temperature) and allows this liquid to be heated in a water bath to a known temperature and escape from a flask through a tiny opening (Giunta‚ 2003). In this situation‚ vapours are assumed to be obeying the

“Hydraulic Fracturing or Fracking is a process in which fractures in rocks below the earth’s surface are opened and widened by injecting chemicals and liquids at high pressure”(Dictionary). This type of mining is used to extract natural gas and oil by drilling a mile or more below the surface. Fracking has been “commercially used for 65 years”(Introduction)‚ supplying Americans energy. Hydraulic Fracturing has allowed for the increase in supplies of oil and natural gas. It is currently the best and

used to separate magnetic substances from waste water. Filtration is a technique that will separate a solid that has not yet dissolved in a liquid. Take a mixture of a solid and liquid and run it through a filter‚ the liquid will pass through the filter and you will be left with the sold. The filter has little holes in it that are small enough to only let liquid through. Filtration is not a technique to separate solids‚ separating solids like that is called sifting. Example of filtration includes your
