Question

You put a bottle of drinking water in a refrigerator and leave it until its temperature has dropped by 5Kelvin. What is its temperature change in Fahrenheit scale?​

Answer 1

Answer:

9 degree F

Explanation:

(0K − 273.15) × 9/5 + 32 = -459.7°F

Answer 2

Given: The temperature of a bottle of drinking water is dropped by 5 K.

To find:  The temperature change in Fahrenheit scale.

Solution:

• Temperature has multiple units in which it can be expressed.
• Examples are Celsius, Kelvin, Fahrenheit, Newton and Réaumur.
• All these units are named after the scientists who discovered it.
• The conversion formulas used for each unit are different.
• The formula used to convert Kelvin to Fahrenheit is as follow.

       $F = (K - 273.15) * \frac{9}{5} + 32$

       $= - 450.67 F$

• So if the temperature drops by 5° in Kelvin, then it drops by -450.67° in Fahrenheit.

Therefore, the bottle's temperature change in Fahrenheit scale is -450.67°.
