Question

At what temperature will kelvin scale reading be double of fahrenheit reading

Answer 1

here is u r answer

The conversion from Fahrenheit to Kelvin is K = 5(F+459.67)95(F+459.67)9. Equating this to 2F and solving gives F ~176.7 ∘F∘F which is ~353.4 K

hope u understand plz mark as brain list

Answer 2

The temperature at which the Kelvin scale reading is double the Fahrenheit reading is 176.69 F = 353.38 K

Given,

At a temperature T, Kelvin Scale Reading = 2 × Fahrenheit Reading

To Find,

The temperature in Kelvin and Fahrenheit (K and F respectively)

Solution,

One degree on the Kelvin scale is equal to 1.8° F on the Fahrenheit system (which is made up of smaller units).

The relationship can be expressed mathematically as K = 273 + (5/9)*(F-32)

Now, we have been given that the temperature on the Kelvin scale is 2 times that on the Fahrenheit scale

⇒ K = 2F

⇒ 2F = 273 + (5/9)×(F-32)

⇒ 18F = 2457 + 5F - 160

⇒ 18F - 5F = 2457 - 160

⇒ 13F = 2297

⇒ F = 2297/13

⇒ F = 176.69° F

⇒ K = 2F

⇒ K = 2 × 176.69

⇒ K = 353.38 K
