Soapy water What affect does adding soap to water have on surface tension? Research: "Soaps and detergents include surfactants‚ that reduce the surface tension of the liquid. This allows the liquid to have a good contact with the material and to remove the dirt from it efficiently." (Kibron.com) "Hydrogen bonding between water molecules leads to many interesting consequences at the visible‚ macroscopic level. For example: the boiling point of water‚ its surface tension‚ and it’s ability to

Water pollution is when the water in lakes‚ rivers‚ oceans‚ and other bodies of water is contaminated. Humans are the main cause for polluting the water. The countries that are most affected by water pollution are: India – The Ganges River China – The Yellow River Central Asia – Amu and Syr Darya Rivers Nepals – Most of the Rivers Pacific Islands Australia Water pollution affects ones physical and emotional health since without drinking water we cannot survive and if the water is polluted

water exists in liquid‚ solid‚ and gaseous states water referred to universal solvent ( bipolar molecule enables it to dissolve a wide variety of substances) ice floats ( temperatures drop molecules come together as a solid‚ elections repell (the molecules get less close thus making the ice have less density than water. If this did not occur ice could sink and destroy living organism. (sea animals) Thermal properties Water resist temperature change‚ due to high specific heat which in turn helps

Importance of Water All living things need water. The Earth is full of water. Water is the most essential element‚ next to air‚ to our survival. Water makes up more than two thirds of the weight of the human body‚ and without it‚ we would die in a few days. There are many water importances in our life to complete daily life and to maintain we body health. Humans and other creatures must drink water to avoid dehydration. Dehydration is defined as a loss or insufficient levels of water and important

Properties of Water Lab # 1 Biology 111 January 23‚ 2011 INTRODUCTION With surface tension it is made possible for items such as paper clips to float on water‚ because a molecule within the mass of a liquid encounters gravity to all adjacent molecules in all directions. When you use surfactant substances this creates hydrogen bonds. Purpose of experiment 1 will be to show that once the surfactant substances hits the hydrogen bond pulls down paper clips. Things

Should water be a service public or a private property ? It takes less than a week for a human to die from lack of water. Water is the single most important substance on the planet; without it‚ life could not exist. It’s as necessary for humans as oxygen. Unfortunately‚ the amount of fresh‚ clean water that is readily available for human use is diminishing at an alarming rate. Currently‚ one sixth of the world’s population‚ over one billion people‚ do not have access to adequate drinking water

about boiling water. If you cover the tin and allow the water and air to cool down‚ the air will cool and contract‚ lowering the pressure in the tin. If it lowers enough‚ the partial vacuum will collapse the walls of the can! The boiling point definitely reduces with air pressure. There is a famous demonstration where boiling water or coffee is drunk‚ the trick is it was in a vacuum chamber where it boiled at room temperature. The actual definition of the boiling point of water is the temperature

on the desalination of water. The desalination of water is very important to human and animal life. For centuries humans have used the process of desalination to obtain water safe for consumption.Various methods of desalination have been produced however only some of those methods are widely used today. Although there are numerous methods of desalination all of them involve three liquid streams: the saline feedwater (seawater or brackish water)‚ low-salinity product water‚ and very saline concentrate
