    Thermometers and Temperature Scales

    Any physical property that depends consistently and reproducibly on temperature can be used as the basis of a thermometer. For example, volume increases with temperature for most substances. This property is the basis for the common alcohol thermometer and the original mercury thermometers. Other properties used to measure temperature include electrical resistance, color, and the emission of infrared radiation.
    As many physical properties depend on temperature, the variety of thermometers is...

    Gas Thermometers and the Kelvin Scale

    The definition of temperature in terms of molecular motion suggests that there should be a lowest possible temperature, where the average kinetic energy of molecules is zero (or the minimum allowed by quantum mechanics). Experiments confirm the existence of such a temperature, called absolute zero. An absolute temperature scale is one whose zero point is absolute zero. Such scales are convenient in science because several physical quantities, such as the volume of an ideal gas, are directly...

    Equipments Used to Measure Body Temperature

    Body temperature can be assessed using various devices and measured in Celsius or Fahrenheit.
    Glass-bulb Thermometer:
    Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...

    Assessing Body Temperature - Tympanic membrane01:14

    Assessing Body Temperature - Tympanic membrane

    Assessing tympanic membrane temperature involves using a tympanic membrane thermometer (TMT). Here is a step-by-step guide:
    Step 1: Begin by practicing good hand hygiene to prevent the transmission of microorganisms.
    Step 2: Turn on the thermometer and wait until the ready sign appears on the screen to ensure accurate measurement.
    Step 3: Slide the probe cover in place to prevent cross-contamination.
    Step 4: Instruct the patient to tilt their head to the side for comfort and check for cerumen...

    Measurement: Standard Units03:38

    Measurement: Standard Units

    Every measurement provides three kinds of information: the size or magnitude of the measurement (a number), a standard of comparison for the measurement (a unit), and an indication of the uncertainty of the measurement. While the number and unit are explicitly represented when a quantity is written, the uncertainty is an aspect of the errors in the measurement results.

    Temperature Measurement Sites01:14

    Temperature Measurement Sites

    A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
    Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...
