Equality of temperature and temperature scales

Equality of temperature

also known as thermal equilibrium, which happens when there is no change occurs in any observable traits after the objects are contacted with each other

Electrical Resistance of hot block

decreases with time & for the cold block it increases with time and, & after a period of time, no further change in RESISTANCE occurs

Height of Mercury

decreases with time & for the cold block it increases with time and, & after a period of time, no further change in HEIGHT occurs

Length of a hot block

decreases with time & for the cold block it increases with time and, & after a period of time, no further change in LENGTH occurs

temperature scale

it is a way to measure temperature relative to a starting point (0 to Zero) & a unit of measurement

Degree

is the division or the space between the fixed points which is divided into equal parts as the bases of thermometer readings.

Celsius

is the first universal temperature scale to be over created

Anders Celsius

a Swedish Astronomer in 1741, that devised the Celsius scale of temperature. It is based on water

0 °C & 100 °C/760 mm mercury

is freezing and boiling point of water

37 °C

is the normal temperature of a human body

Metric system

is the universal system of measurement

Daniel Gabriel Fahrenheit

a german physicist wherein Fahrenheit scale was derived to

Fahrenheit

the second universal temperature scale to be created

United States & England

these are countries that always use Fahrenheit scale of temperature for weather observations and other purposes

32 °F & 212 °F

is the freezing and boiling point of water in Fahrenheit scale

Kelvin (K)

the third temperature scale, which is based on the concept of absolute zero

Sir. William Thompson (Lord Kelvin)

is the person kelvin scale is derived of

Zero point

it corresponds to -273 °C & is referred to as absolute zero at which molecular energy matters are completely absent

°C → K

K = °C + 273.15

K → °C

°C = K - 273.15

°C → °F

°F = °C (9/5) + 32

°F → °C

°C = (°F - 32) 5/9
