Absorption of different cloth diapers Problem The purpose of this experiment is to determine which type of cloth diaper can absorb the most amount of water before coming out in any way (either through the diaper or out the sides). Relevance There are many types of cloth diapers on the market these days. They are very expensive and I believe that most parents would like to buy a cloth diaper that has the most absorption. No one wants to put any diaper on their child that will leak through

INTRODUCTION Vapour absorption refrigeration system is one of the oldest methods of producing refrigerating effect. John Leslie in 1810 kept H2SO4 and water in two separate jars connected together. H2SO4 has very high affinity for water. It absorbs water vapour and this becomes the principle of removing the evaporated water vapour requiring no compressor or pump. H2SO4 is an absorbent in this system that has to be recycled by heating to get rid of the absorbed water vapour‚ for continuous

disadvantages of variable costing Many managers use variable costing for internal reporting and decision making since it has number of advantages (Myers par. 1). First‚ on variable costing reports costs are organized by behavior which makes it easier to understand. Also‚ variable costing statements facilitate cost volume profit (CVP) analysis because it separates cost behavior by fixed and variable. Under variable costing‚ changes in inventory or production do not affect the net operating income. In

The main difference between them is the amount of time that the offender spends behind bars and jails are typically ran by local law enforcement while prisons are either ran by the state or the federal government.

Plant Transport Plants are mostly made up of water. Lettuce is about 94% water and a potato is about 77% water. Plants need water for three main purposes: ------photosynthesis‚ -support -transport of chemicals Water is a raw material for photosynthesis. If water is in short supply‚ the rate of photosynthesis will be limited. Plants need water for support‚ otherwise they wilt. Water is needed to transport many chemicals within plants. Chemicals‚ such as mineral salts‚ dissolve in water and
