preservation‚ and in the last century for lowering the freezing point of water(History of Salt). In pure water 0 degrees celsius is the normal freezing point of water. Ice will melt just as fast the water will freeze. You won’t see the melting and freezing processes as long as they are balanced and equal. Adding salt or any foreign substance to the water upsets the fragile equality between freezing and melting. Less of the water molecules reach the surface of the ice in an amount of given time. The

Osmosis and water potential Aim of the experiment: Finding the water potential of potato. Biological principles: Independent variable: concentration of the solution. Dependent variable: percentage changed in weight of the potato strips. Controlled variable: size of the potato strips‚ it can be controlled by cutting the length of the strips. Procedure: Table 1.

My friend Zach agreed to help me. Today we were watching sharks attack a school of salmon when it happened‚ I felt weirdness. Everything started to warm up‚ like my parents had said. Zach felt it too. Looks like we were going to evaporate together. Other water molecule started to go up around us and then we were floating. Day 2

HYDROSPHERE We all know that water occupies 75% of the Earth’s surface. Water is a component of living cells and every cell in a living organism is made up of almost 75% water and this let the cell to function normally. Life would not exist without water. Water gives habitat meaning the hydrosphere gives a significant place for many animals and plants to exist. Water takes a long time to heat up and it also takes a long time to cool down. This is important in helping to control temperatures

is called simmering. Simmering is cooking the chicken with chicken broth or water. This makes the chicken tender and soft‚ ready to be fried. Firstly‚ rinse each chicken breast. If the breasts are frozen‚ allow them to fully defrost before boiling. The chicken breast can also be defrosted in the microwave‚ in the refrigerator‚ or by soaking it in a bowl of cold water. After defrosting the chicken is soaked in salt water it take the slimly taste out of it. Most Africans do this before cooking any

Toxins in the water become attached to the husk’s carbon surfaces.Over time‚ the attractive charge of carbon surfaces are neutralized‚ making it time to change the filter. There are many types of carbon water filters that can be easy to install and are low in cost. The use of carbon filter media is wide spread‚ both in public and private water systems.

NANOTECHNOLOGY IN WATER PURIFICATION Introduction Nanotechnology is the manipulation of matter on a near-atomic scale to produce new structures‚ materials‚ and devices. This technology has the ability to transform many industries and to be applied in many ways to areas ranging from medicine to manufacturing. Research in nanoscale technologies is growing rapidly worldwide In the case of nanoscale materials‚ the uncertainties are great because the characteristics of nanoscle materials may be different
