Cooling drinks In summer‚ cool drinks and juices like lime juice‚ jal jeera‚ kokam juice or buttermilk are commonly prepared in most Indian homes. Coconut water is another option that is cooling and nourishing.

Factory conditions were harsh in the 1800’s because they had to worked a lot‚ factories had no heating or cooling systems‚ and there were a lot of rapidly movings machines which workers‚ especially children‚ were often hurt by the machines. There were a lot of other things that were bad about this and these are just a few. Factory conditions were harsh in the 1800’s. One reason was that they had to work a lot. Back then the average workday was 11.4 hours and this caused the workers to get tired

ointments used in this study gave warming and cooling effect when applied on the skin since they are used to treat pains of muscles‚ joints or spine. According to Koprowksi et al. (2014)‚ the chemicals that responsible to give the effect of warming and cooling feeling are camphor and menthol‚ respectively. Therefore‚ the absence of these two compounds in the samples indicates that the manufacturers have added other compounds that will give the warming and cooling effects on the skin.

It is well known that an IC engine has an efficiency of about 35-40%‚ which means that only one-third of the energy in the fuel is converted into useful work and about 60-65% is wasted to environment. In which about 28-30% is lost by cooling water and lubrication losses‚ around 30-32% is lost in the form of exhaust gases and remainder by radiation‚ etc. In a Vapour Absorption Refrigeration System‚ a physicochemical process replaces the mechanical process of the Vapour Compression Refrigeration
