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

1. 50 ^oC = ….. ^oF ?

Magani

At standard atmospheric matsa lamba, the freezing point of water is 0 ^oC on the Celsius scale kuma 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 ^oC=32 ^oF da 100 ^oC=212 ^oF. A change of 5 C^o = a change of 9 F^o.

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

T^oF = (180/100) T^oC + 32

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

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

T^oF = (9) 10 + 32

T^oF=90 + 32

T^oF=122

50 ^oC=122 ^oF

2. 86 ^oF = ….. ^oC ?

Magani

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^oC=30

86 ^oF=30 ^oC

3. 50^oC = ….. K ?

Magani

T = T ^oC + 273

T = 50 + 273

T = 323

50 ^oC = ba 323 K

4. 212^oF = ….. K ?

Magani

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^oC=100

212 ^oF=100 ^oC + 273

212 ^oF=373 K

 

5. x ku ^oC = x ^oF

x = ….. ?

1 : Converting Celsius scale into Fahrenheit scale

2 : Converting Fahrenheit scale into Celsius scale

6. 122°F = ….. Celsius

Magani

The conversion between the two temperature scales can be written :

T_C = 5/9 (T_F - 32)

T_C = Zafin jiki 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 abin da ke the liquid temperature.

An sani:

Fahrenheit sikelin (T_F) = 95^oF

Ana so: Celsius scale

Magani:

At a pressure of 1 atm, the freezing point of water is 0 °C while the Fahrenheit scale is 32 ^oF. Conversely, the boiling point of water for the Celsius 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 - 32)

T_C = 5/9 (T_F - 32)

T_C = 5/9 (95 - 32)

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.

Magani

T_C = 100/180 (T_F - 32)

T_C = 5/9 (T_F - 32)

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.

Magani:

T^oF = (180/100) T^oC + 32

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

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

T^oF = (9) 12 + 32

T^oF=108 + 32

T^oF=140
