Converting temperature scales (Celsius scale Fahrenheit scale Kelvin scale)

9 Converting temperature scales (Celsius scale Fahrenheit scale Kelvin scale)

1। 50 ^oC = ….. ^oF ?

उपाय

At standard atmospheric दबाव, the freezing point of water is 0 ^oC on the सेल्सियस पैमाने पर और 32 ^oF on the Fahrenheit scale. At standard atmospheric pressure, the boiling point of water is 100 ^oC on the Celsius scale and 212 ^oF on the Fahrenheit scale.

0 ^oसी = 32 ^oएफ और 100 ^oसी = 212 ^oF. A change of 5 C^o = a change of 9 F^o.

For a Celsius scale, the distance between 0 ^oC और 100 ^oC divided into 100 equal intervals. For a Fahrenheit scale, the distance between 0 ^oC और 100 ^oC divided into 180 equal intervals.

T^oF = (180/100) T^oसी+32

T^oF = (9/5) T^oसी+32

T^oF = (9/5) 50 + 32

T^oF = (9) 10 + 32

T^oएफ = 90 + 32

T^oएफ = 122

50 ^oसी = 122 ^oF

2। 86 ^oF = ….. ^oC ?

उपाय

T^oC = (100/180)(T^oF – 32)

T^oC = (5/9)(T^oF – 32)

T^oC = (5/9)(86 – 32)

T^oC = (5/9)(54)

T^oC = (5)(6)

T^oसी = 30

86 ^oएफ = 30 ^oC

3। 50^oC = ….. K ?

उपाय

टी = टी ^oसी+273

टी = 50 + 273

टी = 323

50 ^oसी = 323 कश्मीर

4। 212^oF = ….. K ?

उपाय

T^oC = (100/180)(T^oF – 32)

T^oC = (5/9)(T^oF – 32)

T^oC = (5/9)(212 – 32)

T^oC = (5/9)(180)

T^oC = (5)(20)

T^oसी = 100

212 ^oएफ = 100 ^oसी+273

212 ^oएफ = 373 K

 

5. एक्स ^oC = x ^oF

x = ….. ?

उपाय

1 : Converting Celsius scale into Fahrenheit scale

2 : Converting Fahrenheit scale into Celsius scale

6. 122°F = ….. Celsius

उपाय

The conversion between the two temperature scales can be written :

T_C = 5/9 (T_F - एक्सएनएनएक्स)

T_C = तापमान in Celsius, T_F = temperature in Fahrenheit

The temperature in Celsius :

T_C = 5/9 (122 – 32) = T_C = 5/9 (90) = 5 (10)

T_C = 50 ^oC

7. The figure below shows the temperature measurement of a liquid with the Fahrenheit scale thermometer! If the temperature of the liquid is measured using a Celsius scale thermometer, then क्या है the liquid temperature.

ज्ञात :

फारेनहाइट स्केल (T_F) = 95^oF

वांछित : सेल्सियस पैमाने पर

समाधान:

At a pressure of 1 atm, पानी का हिमांक is 0 °C while the Fahrenheit scale is 32 ^oF. Conversely, the boiling point of water for the Cएल्सियस scale is 100 ^oC while the Fahrenheit scale is 212 ^oF.

On the Celsius scale, between 0 °C and 100 ° C there are 100 ° while on the Fahrenheit scale between 32 °F to 212 °F there is 180°.

T_C = 100/180 (T_F - एक्सएनएनएक्स)

T_C = 5/9 (T_F - एक्सएनएनएक्स)

T_C = 5/9 (95 - एक्सएनएनएक्स)

T_C = 5/9 (63)

T_C = 315 / 9

T_C = 35^oC

8. Based on figure below, determine the temperature P on the Celsius thermometer.

उपाय

T_C = 100/180 (T_F - एक्सएनएनएक्स)

T_C = 5/9 (T_F - एक्सएनएनएक्स)

T_C = 5/9 (104 – 32)

T_C = 5/9 (72)

T_C = 360 / 9

T_C = 40 ^oC

9. If the temperature of Celsius scale as shown in figure below, determine the temperature of Fahrenheit scale as shown in figure below.

समाधान:

T^oF = (180/100) T^oसी+32

T^oF = (9/5) T^oसी+32

T^oF = (9/5) 60 + 32

T^oF = (9) 12 + 32

T^oएफ = 108 + 32

T^oएफ = 140
