Calorie Definition in Chemistry

Calorie Definition in Chemistry A calorie  is a unit of energy, but whether or not the c in the word is capitalized matters. Heres what you need to know: Calorie Definition A calorie is a unit of thermal energy equal to 4.184 joules or the amount of energy required to raise the temperature of 1 gram of liquid water 1 °C at standard pressure. Sometimes a calorie (written with a lowercase c) is called a small calories or a gram calorie. The symbol for the calorie is cal. When the word Calorie is written with an uppercase C, it refers to the large calorie, food calorie, or kilogram calorie. The Calorie is 100 calories or the amount of thermal energy needed to heat one kilogram of water one degree Celsius. Calorie History Nicolas  Clà ©ment, a French chemist and physicist, first defined the calorie as a unit of heat or thermal energy in 1824. The word calorie comes from the Latin word calor, which means heat. The small calorie was defined in English and French dictionaries around 1841 to 1867. Wilbur Olin Atwater introduced the large calorie in 1887. Calorie Versus Joule The calorie is based on joules, grams, and degrees Celsius, so in a way its a metric unit, but the official unit of energy in the International System of Units (SI) is simply the joule. In the modern era, its more common to express thermal energy in terms of joules per kelvin per gram or kilogram. These values relate to the specific heat capacity of water. While the small calorie is still used sometimes in chemistry and the large calorie is used for food, joules (J) and kilojoules (kJ) are the preferred units.

Character Tags in Fiction

Character Tags in Fiction Character Tags in Fiction Character Tags in Fiction By Maeve Maddox In the parlance of fiction writing, a character tag is a repetitive verbal device used to identify a character in the mind of the reader. More than a simple description, a character tag calls to mind aspects of the characters personality and uniqueness. Uriah Heeps clammy hands, his constant hand rubbing, and his use of the word humble to describe himself and his mother are character tags that make him unforgettable. Sherlock Holmes and his violin, his shag tobacco, and his uncanny aptitude for noting and interpreting details others ignore, are only three of the numerous character tags that make him live in our imagination. Character tags may be drawn from any aspect of the characters appearance or behavior: voice gestures body carriage dialect and speech mannerisms hair clothing scent mental state A sympathetic character who has red hair may be described as having carrot red hair, while a creepy character might have hair the color of dried blood. Some characters in a novel may appear only a few times, but the most minor character needs a character tag or two to make him memorable. In The Mummers Curse Gillian Roberts introduces a minor character with this description: I didn’t recognize him, but I didnt think I should be scared. He was polite, his voice low-pitched and confident, and apparently he knew me. Besides, he was elegant. In his early forties, I thought, with prematurely silver hair uncovered despite the freezing wind, and looking none the worse for it. His topcoat was visibly soft, cashmere, I suspected, and his hands, encased in buttery brown gloves, held a leather-bound book with gold-edged pages. When the character appears again, the author reiterates some of these details, for example, the silver hair that defies the elements, the expensive attire, and the book. C. R. Corwins Morgue Mama Mysteries feature a newspaper librarian in her sixties. Many of her character tags have to do with her appearance: My name is Dolly Madison Sprowls. Im 68 years old. Im short, a little dumpy, and I havent changed my hairstyle since college. I looked up and found Chick Glass. I figured that was you, Maddy, he said. He playfully flicked my Prince Valiant bangs with his fingers. Used judiciously, character tags add dimension to the characters and enable the reader to tell them apart. Depending on what mental baggage the reader brings to the story, however, character tags can jar the reader out of the dream and cause annoyance. In the Amanda Pepper mysteries by Gillian Roberts, Amanda is a native of Philadelphia. Her boyfriend Mackenzie is from the South. One of his character tags is that he lapses into his native speech when stressed. Speech tags involving dialect and speech mannerisms can be effective, but Roberts doesnt just make use of the tag and move on; she has Amanda comment at such length on Mackenzies lapses that I grow annoyed at what seems to me to be a display of a misplaced sense of regional superiority. The Maddy Sprowls character has two character tags that yank me out of the story every time they occur. One is a speech tag and the other involves a habitual gesture. Here are examples: Are you saying Gordon was gay? Good gravy, does everything have to be about sex? She took the brick†¦How much did you pay for it? I pawed the air. It was a steal. Every time I read the interjection Good gravy, I pictured Archie, Jughead, Betty, and Veronica from the comics. I dont know if they said it, but thats what I thought of every time and there are lots of good gravies in Dig. The other tag that never failed to jar is I pawed the air. Maddy paws the air a lot. Every time I read that tag I imagined a rearing horse. I finally decided that Corwin intended to convey the dismissive gesture one might make while saying Pshaw! Character tags are great ways to make fictional characters live, but take care to avoid any that may defeat the purpose of keeping the reader engaged in the story.
