The freezing temperatures for water on the Celsius and Fahrenheit scales are 0ºC and 32ºF, respectively. The boiling temperatures for water are 100ºC and 212ºF. Let C denote the temperature in Celsius and F in Fahrenheit.

Write the conversion function from Celsius to Fahrenheit. Use the function to convert 25ºC into ºF.

Answer :

Answer:

Therefore the required function is

[tex]C= \frac{5}{9} (F-32)[/tex]

Therefore 25°C=57°F

Explanation:

F denotes temperature of Fahrenheit and C denotes temperature of Celsius.

[tex]\frac{C-0}{100-0} =\frac{F-32}{212-32}[/tex]

[tex]\Rightarrow C= \frac{100}{180} (F-32)[/tex]

[tex]\Rightarrow C= \frac{5}{9} (F-32)[/tex]

Therefore the required function is

[tex]C= \frac{5}{9} (F-32)[/tex]

Putting C=25°C in above equation

[tex]25=\frac{5}{9} (F-32)[/tex]

[tex]\Rightarrow 25 \times \frac{9}{5} = F-32[/tex]

⇒45 =F-32

⇒F=32+45

⇒F=57

Therefore 25°C=57°F

The conversion function from Celsius to Fahrenheit is F = (C × 9/5) + 32. Using this, 25°C is converted to 77°F.

The subject of this question is temperature conversion between Celsius and Fahrenheit scales. To create a conversion function from Celsius to Fahrenheit, we use the relationship that a change of 1°C is equivalent to a change of 1.8°F. Since the freezing point of water is 0°C and 32°F, we can derive the following function for converting temperature from Celsius to Fahrenheit:

F = (C × 9/5) + 32.

Using this function, we can convert 25°C into Fahrenheit as follows:

  1. Multiply the Celsius temperature by 9/5: 25 × 9/5 = 45.
  2. Add 32 to the result: 45 + 32 = 77.

Therefore, 25°C is equal to 77°F.
