The temperature of an iron piece is heated from `30^@ C "to" 90^@ C`. What is the change in its temperature on the fahrenheit scale and on the kelvin scale?

Explanation

To solve the problem of finding the change in temperature of an iron piece heated from \(30^\circ C\) to \(90^\circ C\) on both the Fahrenheit and Kelvin scales, we can follow these steps:

### Step-by-Step Solution:

1. **Calculate the Change in Temperature in Celsius:**
\[ \Delta T_C = T_{\text{final}} - T_{\text{initial}} = 90^\circ C - 30^\circ C = 60^\circ C \]
