Question

Assume that the temperature outside is 293 Kelvin but you’re familiar only with the Fahrenheit scale. Do you need to wear a hat and gloves when you go outside? To find out, convert the Kelvin temperature to Fahrenheit. (Hint: Convert the Kelvin temperature to Celsius first.)

Answer 1

Given,

The temperature in Kelvin, T_K=293 K

The temperature can be converted into Celcius using the formula,

`T_C=T_K-273`

On substituting the known values,

`\begin{gathered} T_C=293-273_{} \\ =20\text{ }\degree\text{C} \end{gathered}`

The temperature can be converted from Celcius to Fahrenheit using the equation,

`T_F=(T_C*(9)/(5))+32`

On substituting the known values,

`\begin{gathered} T_F=20*(9)/(5)+32 \\ =68\text{ }\degree\text{F} \end{gathered}`

Thus 293 K in Fahrenheit is 68 °F
