why viscosity decreases with increase in temperature

Viscosity and surface tension are two physical characteristics of a liquid. Viscosity is the measure of how resistant to flow a liquid is, while surface tension is defined as how resistant the surface of a liquid is to penetration. Both viscosity and surface tension are affected by changes in temperature. What is Viscosity? Viscosity is determined by the time it takes a given amount of liquid to flow through an instrument called a viscometer tube; essentially a narrow pipe. A good example of viscosity is liquid flowing through a straw: water, which has a low viscosity, will flow more freely than honey, which has a high viscosity. Liquids like honey have a higher viscosity because they contain more complex molecular structures; while water consists of simple hydrogen and oxygen bonds,

why do we have fish on good friday

Get daily updates directly to your inbox It's a tradition millions of us follow - eating fish on Good Friday. It's as much a part of as and the, only this tradition goes back much further. Christians have abstained from eating meat on Good Friday for centuries and many people, whether or not they are religious, still will only eat fish on the day. In fact many Christians, especially Catholics, won't eat meat on any Friday. The reason behind this tradition is very much a religious one. It's believed Jesus Christ suffered and died on the cross on a Friday, Christians from the very beginning have set aside that day to remember this and 'unite their sufferings'. This led the Church to mark every Friday as a 'Good Friday', where people remember the Passion by offering the 'penance'. Meat was

 why do we need ethics in society

why do we need ethics in society

There are times when the right and wrong decisions are obvious, but what about the times where the outcome is less clear? Situations where, if nobody knew you made the wrong decision, you would benefit financially, emotionally, or otherwise. Ethics help us navigate the gray area between absolute right and morally wrong. They provide the structure that helps us make a decision we can be proud of. For me personally, ethics are the rules that society must adhere to. Descartes may have said БI think, therefore I amБ but it is not only thinking that makes mankind sentient, itБs the ability to think and act ethically. Without ethics, society would be reduced to the type of animal behaviour that is seen in nature. Hunt, kill, feed, fornicate. When mankind started to think about the outcome of

 why do we have bad breath when we wake up

why do we have bad breath when we wake up

Does this sound familiar? You wake up in the morning and quickly cover your mouth with your hand so your partner doesnБt get a whiff of your bad breath. Morning breath, halitosis Б whatever you call it, it can be unpleasant and it probably isn't the way you want to greet your partner, or the day. БEveryone has morning breath to some degree,Б says Sally J. Cram, DDS, a periodontist in the Washington, D. C. , area and a consumer adviser for the American Dental Association. HereБs the simple reason why: When you sleep, your mouth dries out. When your mouth dries out, odor-producing bacteria proliferate. БWhen you sleep, your normal flow of decreases,Б Dr. Cram explains. БThatБs why your breath can be worse in the morning. Б If you snore or breathe through your mouth at night, youБre more

why is my skin itchy but no rash

Itching skin or pruritus can be brought on by any number of conditions. In most cases, a small area of your skin will get to be distinctly irritated for a brief time period; however, at times a wide area of your skin can get to be distinctly affected by this itching.

In some cases, an allergic reaction to foods, makeup or poison ivy can cause the body to create itching on the skin. Drugs Reactions to

 why do we need enzymes in our body

why do we need enzymes in our body

Enzymes work best at your normal body temperature. The average body temperature is 98. 6ВF (37ВC), but normal body temperatures can from 97 to 99ВF (36. 1 to 37. 2ВC). If you run a fever and your temperature increases too much, the structure of enzymes breaks down. They no longer function properly. Restoring your body temperature to its optimal range will help restore enzyme health. Certain health conditions, such as, or inflammation of the pancreas, can also reduce the number and effectiveness of certain digestive enzymes. The pH level of your stomach or intestines can also affect enzyme activity. A low pH means something is very. A high pH means itвs basic or alkaline. Enzymes work best in a fairly narrow pH range. If the environment surrounding an enzyme becomes too acidic or too

 why do the rich pay less taxes

why do the rich pay less taxes

The rich don t really pay that much in tax and to the extent that they do, it s because they get the biggest chunk of the income The government likes to say that the richest 15% of households (those earning over $150,000) pay three-quarters of all the. The problem with this measure is that it isn t really about tax. It does start with the amount of income tax paid by different groups but it then does complicated calculations about how much those groups received in benefit payments, the accommodation supplement, paid parental leave and Working for Families. Those figures are subtracted from the amount of tax paid by each group, to arrive at a strange sort of net financial contribution to the government s books measure. More useful figuresPabout income tax arePin the graph below, which

 why do pain management clinics drug test

why do pain management clinics drug test

Komondor. this is my non-medical and unscientific answer to your question. if you REALLY just took ONE toke off of a joint two weeks before your drug test and did not have any marijuana buildup in your body from previous usage, then I can't see how it will show up. If (and you should) your test does not show any metabolites, then you're good to go. In my opinion, do not "confess" and consider yourself receiving a pass. and you're taking a gamble when trying to time your smoking with your visits because if they decide to call you in for a surprise test as many do a couple of days after you smoke, you're screwed. but you're playing with fire. If your doctor tests for it, and most do, you need to no do it again as you will most probably get canned. and have an extremely hard time being

 why is my jade plant losing leaves

why is my jade plant losing leaves

Greenish, If water runs out by the time your out of water, that sounds ok. If the roots are growing out the bottom, or in a mass circle, it should have a bit larger pot. If the pot is too small the soil can dry out rather quickly, within days of watering, not giving the roots a chance to drink up enough water to stay healthy. Like mentioned, the roots should have at least an inch or two of soil all the way around, if you have anything less, or more, you can have dried up roots, or rot, but you do want the roots on the snug side. For cactus and succulents, I like to use clay because they are porous. Keep in mind, plastic pots will hold water longer. Water meters are not always accurate, and can give false readings. The best way to tell if a plant needs water is by using your finger,
