 why do we use the kelvin scale

why do we use the kelvin scale

The Kelvin temperature scale was the brainchild of Belfast-born British inventor and scientist William Thomson also known as Lord Kelvin. It is one of the three best-known scales used to measure temperature, along with Fahrenheit and Celsius. Like other, the freezing and boiling points of water are factors in establishing the scale s range. There are 100 degrees between the temperate at which water freezes at (273. 16 K) and boils (373. 16 K). Each unit on this scale, called a Kelvin rather than a degree, is equal to a degree on the. For this reason, just the K, not the degree symbol, is used when reporting temperatures in Kelvin. There are no negative numbers on the Kelvin scale, as the lowest number is 0 K. The idea for the Kelvin scale was sparked by a discovery in the 1800s of a

why do we wake up with bad breath

The unpleasantness of morning breath leads you to quickly cover your mouth when you pass your loved ones in the morning. You realize no amount of brushing, flossing, or mouthwash the night before seems to mask the overwhelming odor from your mouth when you wake up. Getting out of bed with bad breath, halitosis, in the morning is fairly common as our mouth goes into a Бrest and digestБ mode overnight. Up to 80 million people, according to the, suffer from bad breath that is ever-present, while millions of Americans suffer from bad breath in limited situations such as in the morning or after eating pungent food. People who suffer from dry mouth often due to taking certain medications or mouth breathers are more prone to morning breath. Those with poor oral hygiene will also suffer from bad

 why do your eyes get red when you cry

why do your eyes get red when you cry

It's a fairly popular assumption that men and women express their emotions differently and this is especially true when it comes to crying. Research shows major gaps in how often men and women cry. A recent study found women cry 47 times per year while men, on average, reported only crying 7 times per year. Where does this disparity come from? Well, societal pressures and cultural norms are likely at play here. American culture, for instance, has a long history of encouraging men to release their anger and emotions through physical aggression. Women, on the other hand, tend to be stereotyped as overly emotional and criticized for crying too much. Still, why the ugly cry face? When we cry, our lacrimal glands have to produce tear fluid, a process supported by increased blood flow to our

 why do we test new drugs on animals

why do we test new drugs on animals

Monkeys, dogs, rabbits, rats and mice have been used to test drugs for humans for over half a century. Laws and regulatory agencies worldwide currently require that medicines are tested on animals before clinical trials on humans. Millions of animals are used in these cruel tests worldwide every year. Approximately 250,000 animals were used in 2016 in Britain alone. This is on top of the millions of animals used in more basic medical research. The majority of dogs and monkeys in laboratories are used for drug safety testing. For example, 54% of all dog experiments and 81% of all monkey experiments in the UK in 2016 were for safety testing human medicines. But until recently, scientists knew very little about whether experiments on animals are actually useful in developing drugs for

Throughout the history of the world there has been an ongoing conversation of the ideas andP values that shape our society and have shaped each successive society. P If you want to take part of this "Great Conversation" of ideas that underlie the very world that we live in - our governments, our religions, our culture, our entertainment, and our economy, you need to understand the conversation that has happened previously before you can truly jump into its current. P If you have ever tried to jump into a conversation in the middle - you should see how awkward that can be - you will often merely rehash old ideas that have already been said. P This conversation was not played out in speech, it has been played out in the great works of literature, philosophy, and history. ...

 why do trees die when bark is removed

why do trees die when bark is removed

Issue: September 8, 2007 Our dog ate most of the bark off the base of our apple tree the other day. К Will this kill the tree? К Can I save it? Answer: When a tree has been damaged by removing a ring of bark, the tree may die depending on how completely it was girdled. Removal of even a vertical strip of bark less than one-fourth the circumference of the tree will harm the tree, but not kill the tree. When the patch of bark is one-half or greater, the chances of tree death increase. Complete girdling (the bark removed from a band completely encircling the tree) will certainly kill the tree. The reason for damage due to girdling is that the phloem layer of tissue just below the bark is responsible for carrying food produced in the leaves by photosynthesis to the roots. Without this food,

Why is Sweet Caroline the Boston Red Sox Theme Song? by April 22, 2013 11:24 AM Shortly after the Boston Marathon bombings, I was at a Binghamton Senators game and the song Sweet Caroline was played in honor of the victims of the Boston Marathon bombings. A couple days later, a friend who lives in Boston told me that she was at a game at Fenway when Neil Diamond himself showed up unannounced and asked permission to sing Sweet Caroline to the Red Sox fans at the game. Just another reason why I have an old enough to be my father, but I don t care crush on Neil. But that s beside the point. If you re not a Red Sox fan, you probably have no clue why Sweet Caroline has special meaning to the people of Boston. I know that I didn t, so decided to search for the answer. According to, Sweet

 why do we need laws in society

why do we need laws in society

What is a Law? DonБt run with scissors in your hand! DonБt drive your car on the sidewalk! Do not steal your neighborБs property! How many times a day does someone tell you what to do? How often do you have to stop yourself from doing what you want, because you know that this action is prohibited or wrong? In the United States, it seems like we have laws, rules, and regulations to oversee just about everything. We donБt always like these rules, since they often mean that someone is telling us what to do, or keeping us from doing what we want. Yet to live in a civil society, we must have some rules to follow. Who gets to make these rules? Where do they come from? What happens when we break them? These are the questions this page will seek to answer for you. aws are rules that bind all
