Temperature conversion is the process of changing a temperature from one unit to another, such as Celsius, Fahrenheit, or Kelvin, without changing the actual temperature.
Sample Problems
Question 1: Convert the temperature 20°C to Fahrenheit using the Temperature conversion formula.
Solution:
Given, Celsius (C) = 20°C
Fahrenheit (F) = C × (9/5) + 32
= 20 × (9/5) + 32
= 36 + 32
= 68°F
Therefore 20°C = 68°F
Question 2: Convert the temperature 50°F to Celsius using the Temperature conversion formula.
Solution:
Given, Fahrenheit (F) = 50°F
Celsius (C) = (F - 32) × (5/9)
= (50 - 32) × (5/9)
= 18 × (5/9)
=10°C
Therefore 50°F = 10°C
Question 3: Convert the temperature to 32°C to Kelvin using the Temperature conversion formula.
Solution:
Given, Celsius (C) = 32°C
Kelvin (K) = C + 273.15
= 32 + 273.15
= 305.15K
Therefore 32°C = 305.15K
Question 4: Convert the temperature 275K to °C using the Temperature conversion formula.
Solution:
Given, Kelvin (K) = 275K
Celsius (C) = K - 273.15
= 275 - 273.15
= 1.85°C
Therefore 275K = 1.85°C
Question 5: Convert the temperature 59°F to Kelvin using the Temperature conversion formula.
Solution:
Given, Fahrenheit (F) = 59°F
Kelvin (K) = (F - 32) × (5/9) + 273.15
= (59 - 32) × (5/9) + 273.15
= 27 × (5/9) + 273.15
= 3 × (5) + 273.15
= 15 + 273.15
= 288.15K
Therefore 59°F = 288.15K
Question 6: Convert the temperature 300K to Fahrenheit using the Temperature conversion formula.
Solution:
Given, Kelvin (K) = 300K
Fahrenheit (F) = (K - 273.15) × (9/5) + 32
= (300 - 273.15) × (9/5) + 32
= 26.85 × (9/5) + 32
= 48.33 + 32
= 80.33°F
Therefore 300K = 80.33°F
Practice Problem
Question 1. First, convert -40°F to Kelvin, and then to Celsius. In Celsius, what is the final temperature?
Question 2. In a laboratory experiment, a scientist records a temperature of 150°C. Convert this temperature to Kelvin and Fahrenheit. Next, figure out how much the Celsius and Kelvin values differ from one another.
Question 3. Water has a boiling point of 212°F. Determine the difference between the two converted temperatures by converting this one to both Celsius and Kelvin.
Question 4. A desert location records a temperature of 100°F. After that, the temperature is raised by 30°C. Determine the difference between the two Kelvin values after converting the temperatures (before and after the increase) to Kelvin.
Answer:-
- 233.15 K, -40°C
- 423.15 K, 302°F
- Difference between Celsius and Kelvin: 273.15 K, 100°C, 373.15 K
- 310.93 K, 303.15 K, 7.78 K
