Thermometers: Understand the options Thermometers come in a variety of styles. Understand the different types of thermometers and how to pick the right thermometer for you.By Mayo Clinic Staff Choosing the thermometer that’s best for your family can be confusing. Here’s what you need to know about the most common thermometers. Digital thermometers Regular digital thermometers‚ which use electronic heat sensors to record body temperature‚ can be used in the rectum‚ mouth or armpit. The most accurate

Thermometers measure temperature‚ by using materials that change in some way when they are heated or cooled. What can be considered the first modern thermometer‚ the mercury thermometer with a standardized scale‚ was invented by Daniel Gabriel Fahrenhei[->0]t in 1714. The Celsius temperature scale is also referred to as the "centigrade" scale. Centigrade means "consisting of or divided into 100 degrees". In 1742‚ the Celsius scale was invented by Swedish Astronomer Anders Celsius[->1].

Thermometer is the device used to measure temperature. The extremely fine tube (narrow bore) of a thermometer is called a capillary. The boiling point of water (or condensing point of steam) is 100oC or 212oF or 373 K. The freezing point of water (or melting point of ice) is 0oC or 32oF or 273 K. These temperatures are typically used in the calibration of thermometers and are known as the fixed points. The temperature range that is typically marked on a laboratory thermometer is −10oC to 110oC

Disposable Diapers John Smith Environmental Science with Lab SPRB12 - Sec C Professor Mukami Disposable diapers came about during World War II‚ as there was a shortage of cotton to make cloth diapers. One of the first diapers to be developed was a plastic covering that was made from a shower curtain and had layers of tissue paper as an absorbent lining. During the 1970’s the demand for disposable diapers had increase and there were improvements made to reduce the bulkiness

Noah Borel Thermometers A thermometer is a device or instrument used for measuring temperature. There are many different types of thermometers; however each one is based on a physical property of a thermometric (temperature measuring) substance that differs in a measurable way with temperature. Some of the physical properties that vary with temperature are volume‚ resistance and color. A physical property that increases or decreases with temperature can be used to measure temperature.

Different types of thermometers Galileo thermometer. A Galileo thermometer (or Galilean thermometer)‚ named after Italian physicist Galileo Galilei‚ is a thermometer made of a sealed glass cylinder containing a clear liquid and a series of objects whose densities are such that they rise or fall as the temperature changes. By definition‚ Galileo’s thermometer is actually a thermoscope‚ not a thermometer. Gas thermometer A gas thermometer measures temperature by the variation in volume

Science Behind the Galileo Thermometer The Galileo thermometer‚ used to measure temperature‚ is mainly used for home décor nowadays. The stylish thermometer used in people’s homes today is based off of a thermo scope Galileo invented in the early 1600’s. Although not exact‚ the Galileo thermometer is moderately accurate. The thermometer has several glass blown bubbles‚ with a colored liquid inside which is just for decoration. The bubbles have metal tags attached to the bottom of them with an engraved

Temperature and Thermometers The Temperature of an object is a measure of the hotness or coldness of that object. An alternative way to think of temperature is to say that “the temperature of an object is a number – on some manmade scale – that indicates the hotness of the object”. ‘Hotness’ in turn is a measure of the kinetic energy of the molecules of the material. Note: You must use the term ‘hotness’.* The SI unit of temperature is the Kelvin (K)* Relationship between degrees Celsius

Disposable Society I quite agree with the statement “we live in Disposable society”. During my school years and college years‚ I often heard about foreign countries also I noticed that they stressed its cleanliness. My friends and relatives told me that if we want to live in a healthy and clean environment we have to go to foreign countries such as America‚ London‚ Singapore. I always had a dream to live in theses nice countries. My dream became true now. Ten years ago‚ when I arrived
