A thermometer is used to measure Temperature.

» Extra info «

• Temperature is the measure of the hotness or coldness of a body.
• Temperature helps in understanding the flow of heat between two bodies or two systems.

• The SI unit of temperature is Kelvin (K)

$\textbf{Thermometers}$

• We use different types of thrmometers , depending an object of which temperature is to be measured.

• The two commonly used thermometer has a clinical thermometer and laboratory thermometer.

$\textbf{Clinical\: Thermometer}$

• The clinical thermometer is designed to measure the temperature of human body.

$\textbf{Laboratory\: Thermometer}$

• Laboratory thermometer is used in laboratories to measure the temperature of different susbtances and the environment around us.

• It is also used to find the boiling and melting point of various substances.

$\textbf{Six's\: Thermometer}$

• The meteorology department uses a special type of thermometer called the Six's Thermometer.

• It is specifically helps in recording the minimum and maximum temperature over a desired time period.

Therefore the answer is

Option a.

Answer 2

$\Huge{\textbf{\underline{\underline{Answer;}}}}$

★$\large{\textbf{\textsf{Option a) \: Temperature}}}$

★ Temperature is a physical quantity expressing hot and cold.

★It is measured with a thermometer calibrated in one or more temperature scales.

★Thermometer is invented by Daniel Fahrenheit.

★ The most commonly used scales are Celsius scale, fahrenheit scale and the Kelvin scale.

★Kelvin scale (K) is the SI unit of temperature.

★$\textbf{Thermometer}$ has two important elements:

(1) $\textbf{\textsf{a\: temperature\: sensor}}$ and

(2) $\textbf{\textsf{some\: means\: of \:converting\: this \:change\: into \:a\: numerical\: value \:in\: a\: digital\: thermometer.\:}}$
