The Rankine temperature scale $\left({ }^{\circ} \mathrm{R}\right)$ is an engineering temperature scale with $0.00^{\circ} \mathrm{R}$ at absolute zero and the same degree size as the Fahrenheit scale. Convert $82 \mathrm{~K}$ to ${ }^{\circ} \mathrm{R}$ : ${ }^{\circ} \mathrm{R}$

Step 1 ：The Rankine temperature scale (°R) is an engineering temperature scale with 0.00°R at absolute zero and the same degree size as the Fahrenheit scale.

Step 2 ：We are asked to convert 82 K to °R.

Step 3 ：To convert Kelvin to Rankine, we can use the formula: \( R = K * \frac{9}{5} \) where R is the temperature in Rankine and K is the temperature in Kelvin.

Step 4 ：In this case, K = 82.

Step 5 ：Substituting K = 82 into the formula, we get \( R = 82 * \frac{9}{5} = 147.6 \)

Step 6 ：Final Answer: The temperature in Rankine is \(\boxed{147.6}\)
