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

Protection and Security The separation of protection and security is a design choice. Protection is identified as a mechanism‚ which means that it is a device that changes an input into a desired output. Security is identified as a policy‚ which is a procedure to guide the decision making process. Security relies on the protective mechanisms along with cryptology techniques. Protection has security policies that are supported by protective mechanisms and decides

Surface Water - Surface water is water on the surface of the planet such as in a stream‚ river‚ lake‚ wetland‚ or ocean. It can be contrasted with groundwater and atmospheric water. - Non-saline surface water is replenished by precipitation and by recruitment from ground-water. It is lost through evaporation‚ seepage into the ground where it becomes ground-water‚ used by plants for transpiration‚ abstracted by mankind for agriculture‚ living‚ industry etc. or discharged to the sea where it becomes

and soil microbes. In some complex forests‚ there is also a well-defined lower tree layer. Forests are central to all human life because they provide a diverse range of resources: they store carbon‚ aid in regulating the planetary climate‚ purify water and mitigate natural hazards such as floods. Forests also contain roughly 90 percent of the world’s terrestrial biodiversity.[3] ---------------------------------------------------------------------------------------------------------------------

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
