Temperature MEASUREMENT

2. DEFINITION OF TEMPERATURE
Temperature (sometimes called thermodynamic temperature) is a measure of the
average kinetic energy of the particles in a system. Adding heat to a system causes its
temperature to rise. ... Temperatures are commonly measured in the Kelvin or Celsius
scales, with Fahrenheit still in common use in the Unites States.
OR
Temperature is a measure of how hot or cold something is; specifically, a measure of
the average kinetic energy of the particles in an object, which is a type of energy
associated with motion. ... The terms hot and cold are not very scientific terms.
What are examples of temperature?
For example, you say that a glass of boiling water is hotter than the ice cream. Be
careful, ice cream is our reference matter. We measure temperature of matters with a
device called thermometer. There are three types of thermometer, Celsius
Thermometer, Fahrenheit Thermometer and Kelvin Thermometer.

3. What is a normal body temperature?
The average normal body temperature is generally accepted as 98.6°F (37°C). Some
studies have shown that the "normal" body temperature can have a wide range, from 97°F
(36.1°C) to 99°F (37.2°C). A temperature over 100.4°F (38°C) most often means you
have a fever caused by an infection or illness.
What is the property of temperature?
Temperature is a physical property of matter that quantitatively expresses hot and cold. It
is the manifestation of thermal energy, present in all matter, which is the source of the
occurrence of heat, a flow of energy, when a body is in contact with another that is colder.
Temperature is measured with a thermometer.
How do you read temperature?

6. Example -1:-Convert the absolute zero of temperature (–273.15 °C), to degrees
Fahrenheit.
F = (9/5)C + 32 = (9/5)×(-273.15) + 32 = -459.67 °F ≈ -460 °F
Example -2:-Convert 86 °F into degrees Celsius, Rankine and Kelvin.
C = (5/9)(F – 32) = (5/9)×(86 – 32) = 30 °C
R = F + 460 = 86 + 460 = 546 R
K = C + 273 = 30 + 273 = 303 K
Example -3:-Determine the temperature in degrees Fahrenheit that would
translate into the same value in degrees Celsius.
set C = F:
F = (5/9)(F – 32) ⇒ 9F = 5F – 160 ⇒ 4F = -160 ⇒ F = -40 °F
Example -4:-Convert 0 °F to degrees Celsius.
C = (5/9)(F – 32) = (5/9)(0 – 32) = -17.78 °C
