water came from outer space to Earth. The water was brought to the planet for the comets. The water has a different structure for each state (gas‚ liquid‚ ice). Liquid water has random molecules. On the other hand‚ the ice has a more stable structure. The different structure between ice and liquid water can explain why the ice has less density than liquid water. Temperature is responsible for increasing the dissolution of components‚ and electrical conductivity. Pure water is not a good conductor‚

CHAPTER I INTRODUCTION A. BACKGROUND OF THE STUDY The Banana is a kind of herb that is usually consumed as either food or flavouring. Its peel is often deemed as useless or without any use that it is just thrown away. But are banana peels as useless as people think? Banana Peels have Potassium (K) that commonly helps clean your body and is used to manufacture soap. Today‚ many fishes have been dying due to polluted waters and careless oil spills. Fishes are a food source

Acetone/Chloroform Liquid-Vapor Phase Diagram Abstract: Liquid-vapor phase of acetone/chloroform was studied through distilling a series of mixtures with different mole fraction. When the mixtures were boiling‚ their vapor was condensed through a water column and collected in a receiving container. Refractive index was collected for starting mixture‚ distillate and residue for each sample. A boiling temperature versus acetone’s mole fraction was constructed to show the liquid-vapor phase diagram

Determining the accuracy of varieties of pipettes by weighing and finding the density of a liquid Abstract Different varieties of pipettes (P100‚ PR1000 pipettors and a serological pipette) along with a weighing balance was used in this investigation to check the density of an unknown liquid by first finding out what the liquid weighed and plotting a graph of the mass in grams against the volume of the liquid used in micro litres (µl) and finding the gradient of the graph (∆Y/∆X). Most of the standard

OF DETTOL ANTISEPTIC LIQUID ON THE GROWTH OF E.COLI Background: Escherichia coli are rod shaped‚ gram negative bacteria often found in the gut of humans and other warm-blooded mammals (Jacques & Ngo‚ 2004). It is transmitted primarily through faecal contaminated food and water. Most strains of E. coli are not harmful to humans‚ however some strains are pathogenic and can cause symptoms including diarrhoea (Unknown‚ 2012). The active ingredient in Dettol Antiseptic Liquid is 4.8% chloroxylenol

The 21st Century Energy Solution: Liquid Flouride Thorium Reactor Recently the spotlight has been set on renewable energies to assist with weaning off of greenhouse gas emissions‚ solving issues with energy independence‚ and to exploit their inherent renewability. Unfortunately our technology is not quite up to speed economically with our wish to rely completely on renewable energy‚ thus many non-renewable energies are recognized as viable options to power our economy (Fraser‚ 2011).

This watershed is now being threatened by expanding vegetable farms‚ creeping banana and pineapple plantations‚ illegal logging and other deleterious undertakings. A portion of the Mt. Talomo-Lipadas watershed‚ some 530 hectares inside the Mt. Apo Natural Park‚ has already been denuded (DCWD). Mt. Talomo-Lipadas watershed‚ the primary source of water in Davao City‚ is now in danger of expansion and encroachment of banana plantations in its protected area‚ especially at the foot slopes of Mt. Apo and

Thermometer Works - pg. 23 Purpose: What makes the liquid within a thermometer go up and down? Hypothesis: If the liquid is placed into objects of different temperatures‚ then the liquid moves up in the hotter substance and down in the colder substance‚ because of the change in the molecular energy when the water is hot and when the water is cold. Materials: Test tube‚ about 20 mL Isopropyl rubbing alcohol‚ 91% Small cup 2 small disposable water bottles (8 oz.) or 2 small beakers Food

Nat Turner was a highly intelligent African American. Even as a young boy his family‚ masters‚ and others noticed his talents. Turner believed he was unfit to be a slave and that he was a profit due to the fact that he taught himself how to read‚ the mark on his head and chest and finally the revelation instructing him to seek the kingdom of Heaven. He took these as signs to become a leader and end slavery in Virginia. Nat Turner’s rebellion was believed to be one of the largest slave rebellions
