Question

1. What are different thermometer scales ? explain.


2. With the help of clinical thermometer measure the temperature between your fingers, under the tongue, armpit, folded hands , folded legs. Write your observations.​

Answer 1

$\boxed{ \sf \pink{info \: about \: thermometer}}$

$\huge \star \: \sf{thermometer}$

= The temperature measuring instruments are called thermometer.

$\boxed{ \star \rm{types \: of \: thermometers}}$

$\sf \blue{liquid \: thermometer}$

= They are based on the principle of change of volume with rise of temperature.

$\rm \blue{ex = mercury \: and \: alcohol \: thermometer}$

$\sf \green{gas \: thermometer}$

they are based on the principle of change of volume of pressure with change in temperature.

ex= constant volume gas and constant pressure gas thermometer.

$\sf \red{platinum \: resistance \: thermometer}$

this is based on the principle of change of electrical resistance with increase of temperature.

Measuring temperature range= -200°C to 1200° C.

$\sf \orange{clinical \: thermometer}$

this thermometer read from 96°F to 110°F.

temperature of human body can be measured with this thermometer.

$\bold \star{\sf{1st \: answer}}$

$\boxed{\sf {\green{thermometer \: scale}}}$

• Celsius scale -C
• Fahrenheit Scale -F
• Reaumer Scale- R
• Kelvin Scale - K

$\huge\bold{celsius \: scale}$

the upper and lower fixed point of this scale are 100°C and 0°C respectively and the fundamental interval is 100.

$\huge \bold{fahrenite \: scale}$

the upper and lower fixed point of the scale are 212°F and 32°F actively and the fundamental interval is 180°.

$\huge \bold{reaumer \: scale}$

the upper and lower fixed point of this scale are 80° R and 0° R respectively and the fundamental interval is 80°.

$\huge \bold{kelvin \: scale}$

the upper and lower fixed points of Kelvin scale are 373K and 273K respectively and the fundamental interval of 100.0K is called absolute zero below which no temperature can be envisaged.
