Thermometers and temperature scales

THERMOMETER:

Thermometer is a device, used to measure temperature.

There are different types of thermometers for different purposes. E.g. A clinical thermometer is used to measure the temperature of human body.

SCALES OF TEMPERATURE:

Thermometers have a scale marked on them. The scale help us give a numeric value to the temperature.

The three commonly used temperature scales are:

1. Celsius scale (Mostly used for environmental measurements)

2. Fahrenheit scale (Mostly used for clinical measurements)

3. Kelvin scale (Mostly used for industrial measurements)

INTERCONVERSION OF SCALES:

These three scales of temperature are interconvertible.

Therefore temperature measured in Celsius scale can be converted into Kelvin and Fahrenheit.

1. Celsius to Kelvin

$\boxed{K=Teperature \; in \; \degree C + 273}$

e.g.

$100 \degree C \;to \;K$

$K= 100 \degree + 273$

$100 \degree C = 373 \,K$

1. Celsius to Fahrenheit

$\boxed{\degree F=1.8(Temperature \;in \; \degree C) + 32}$

e.g.

$0 \degree C \; to \; \degree F$

$\degree F = 1.8 (0\degree)+32$

$\degree F = 0 +32$

$0\degree C = 32 \degree F$
