The importance of water Water is one of the weirdest compounds known to humans. The difference between the boiling point and freezing point of water is one of the largest ranges of any compound. It is this span of temperature that mirrors the range of where life can exist‚ from bacteria to humans. Water also has a very high specific heat‚ which means that it can absorb or lose much heat before its temperature changes. This is important in maintaining body heat in mammals. It also takes a lot of

In most developed countries‚ the water supplied to households‚ commerce and industry meets drinking water standards‚ even though only a very small proportion is actually consumed or used in food preparation. Typical uses (for other than potable purposes) include toilet flushing‚ washing and landscape irrigation. Chlorination is the process of adding the element chlorine to water as

determine how an excess amount of liquid‚ which was water‚ Gatorade and wine in this case‚ along with an excess amount of solute‚ which was the 7g NaCl pill‚ would affect the kidneys and the osmolarity of urine. Measurements of urine volume‚ specific gravity and chloride concentrations were recorded in order to investigate this. Our hypothesis stated that the volume of urine would increase for all groups other than the group drinking 80 ml of water along with taking a 7g. This portion of the hypothesis

The Experiment First‚ I found two 1litre bottles and marked one with ‘+ salt’ and the other with ‘fresh’. I then went on to add red food colouring to the fresh bottle and yellow to the + salt bottle. The reason for doing so was to establish which ones were which and see if they
