A thermometer is an instrument used to measure temperature by using a sealed glass tube containing a liquid such as mercury or alcohol that expands and contracts based on temperature changes. Early thermoscopes led to the development of thermometers using various liquids in glass tubes. Key contributors included Galileo, who invented the first thermometer in 1593, and Fahrenheit and Celsius, who developed standardized temperature scales. Modern thermometers include mercury, alcohol, minimum, maximum, and infrared types and are used to measure temperature, determine weather conditions, and predict weather.

Thermometer and Its Types
There are several types of thermometers described in the document. Mercury thermometers measure temperature by the expansion and contraction of mercury when exposed to heat and cold. They are being phased out due to the hazards of mercury. Digital thermometers use an electronic sensor and LCD display, avoiding mercury. Other types include ear, infrared, and forehead temperature indicators. Proper use involves cleaning, placement in the mouth, rectum, armpit or forehead, and reading the temperature display.

Thermometer
This presentation discusses different types of thermometers and temperature scales. It introduces liquid, gas, resistance, and thermoelectric thermometers. It then explains four main temperature scales - Kelvin, Celsius, Fahrenheit, and Rankine - including their defining points and the scientists who developed them. Relationships between the different temperature scales are also noted.
Fundamentals of Thermometer
This document provides information about different types of thermometers. It begins by defining a thermometer as an instrument that measures temperature quantitatively. Galileo is identified as inventing the first thermometer in the 1600s based on the principle of expansion and contraction with temperature. Thermometers are classified as primary or secondary, with secondary thermometers requiring calibration against primary thermometers. Examples of specific thermometers described include the Galileo thermometer, medical thermometer, Beckmann differential thermometer, bi-metal mechanical thermometer, mercury-in-glass thermometer, and alcohol thermometer.
Temperature
Temperature is a measurement of heat or cold expressed on a scale, with the most common scales being Celsius, Fahrenheit, and Kelvin. Celsius uses 0°C as the freezing point of water and 100°C as the boiling point. Fahrenheit uses 32°F and 212°F as these points. Kelvin uses 0K as absolute zero. Normal human body temperature is around 37°C or 98.6°F measured orally. Temperature is regulated by the hypothalamus and can be influenced by factors like exercise, age, and menstruation. Elevated temperature is a fever while lowered temperature is hypothermia.
Types of thermometer
This document discusses several types of thermometers:
- Digital thermometers use sensors like RTDs, thermocouples, or thermistors to digitally display temperature.
- Tympanic (ear) thermometers use infrared rays to measure the temperature inside the ear canal from a distance.
- Infrared thermometers also measure temperature from a distance by detecting infrared thermal radiation emitted by an object.
- Strip-type thermometers use thermochromic liquid crystals in plastic strips that change color to indicate temperature.
- Mercury and clinical thermometers measure temperature using the expansion and contraction of mercury in a glass tube.
- Laboratory thermometers are used to precisely measure temperature in scientific experiments

Body temperature is regulated by balancing heat production and heat loss. The normal human body temperature ranges from 97-99°F orally and 36.1-37.2°C rectally. Temperature is precisely controlled through neural, vascular, behavioral and other physiological mechanisms. Fever is defined as a temperature above the normal range due to infection, illness or other causes, while hypothermia is a temperature below 35°C due to cold exposure or other factors. Nursing care focuses on monitoring temperature, providing supportive care and rewarming or cooling interventions as needed to maintain a normal temperature range.

Thermometers
Thermometers measure temperature using thermometric properties that change predictably with temperature such as the length of a mercury column, resistance of a wire, or pressure of a gas. Different thermometers use different thermometric substances and properties to develop temperature scales based on fixed points like the melting and boiling points of water. While individual thermometer scales may disagree, defining a standard thermometric substance, property, and scale removes these disagreements. Common thermometers include liquid-in-glass, gas, resistance, thermistor, and thermocouple thermometers.
Temperature
1. To calibrate a thermometer, two fixed points are required - a lower fixed point (melting ice at 0°C) and an upper fixed point (boiling water at 100°C). The temperature scale is marked between these two points.
2. Liquid-in-glass thermometers and thermocouples can measure a wide range of temperatures. Liquid-in-glass thermometers use the expansion of liquid along the glass tube to indicate temperature.

Thermometer
The document discusses different types of thermometers - a mercury thermometer used to measure human body temperature, a maximum/minimum thermometer invented by James Six for use in greenhouses, and a digital thermometer circuit that uses a 1N4148 diode as the temperature sensor and a digital multimeter to display the measured temperature.
Weather
Various instruments are used to measure different weather elements. Thermometers measure temperature, barometers measure atmospheric pressure, hygrometers measure humidity, and anemometers measure wind speed. Thermometers use liquid-in-glass or electronic sensors, barometers provide pressure measurements in millibars, hygrometers can use sling psychrometers or changes in hair length, and anemometers have cups or propellers that spin faster with increasing wind speed. These instruments are important tools for meteorologists to monitor weather conditions.

Hygrometer pd2
A hygrometer is an instrument used to measure humidity. It has been improved over time from early versions built by da Vinci and Folli to modern electronic hygrometers. Hygrometers work by measuring things like the difference between wet-bulb and dry-bulb temperatures or electrical resistance. They are used to monitor humidity in various applications like incubators and museums. Common types include mechanical, electronic, dew point, and chemical hygrometers.
Difference between Clinical And Laboratory thermometer
Clinical thermometers are meant for measuring human body temperature between 35-42°C, while laboratory thermometers can measure a wider range from -10-110°C for uses like checking boiling points. Clinical thermometers were invented in the 1830s by Sir Thomas Clifford Allbutt and first manufactured in 1867, while laboratory thermometers were invented earlier in 1612 by Santorio Santorini and could measure a broader temperature range than clinical thermometers. The key difference is that clinical thermometers are designed specifically for human body temperature measurement whereas laboratory thermometers have a greater temperature measurement range for scientific and laboratory uses.

When air rises and expands, it cools through adiabatic processes. This cooling can cause water vapor in the air to condense into clouds and precipitate out as rain, snow, sleet or hail depending on temperature levels. Clouds are classified based on their height and physical structure into cirrus, altostratus and nimbostratus clouds that form at high, middle and low altitudes respectively.
3jlaubach
Unequal heating of the Earth's surface causes air temperatures to change without a change in energy. This leads some parts of the Earth to be warmer or cooler than others. When warm air rises and is blocked or forced upward by cooler air, various cloud types can form through condensation. Precipitation occurs through processes like collision-coalescence in warm clouds or Bergeron process in mixed-phase clouds, forming rain, snow, sleet, hail, or freezing rain depending on temperature.
