Question

absolute zero is
-459°f on the fahrenheit scale
-273°c on the celsius scale
0k on the kelvin scale
220°r on the rankine scale

Explanation:

To determine the correct option for absolute zero:

• Absolute zero in Kelvin is \( 0\,\text{K} \) (this is the definition of absolute zero on the Kelvin scale).
• For Fahrenheit: The formula to convert Kelvin to Fahrenheit is \( F=\frac{9}{5}(K - 273)+32 \). At \( K = 0 \), \( F=\frac{9}{5}(- 273)+32=-459.4^{\circ}\text{F}\approx - 459^{\circ}\text{F}\), but the option says "\(-459^{\circ}\text{F}\) on the Fahrenheit scale" which is close but let's check others.
• For Celsius: Absolute zero in Celsius is \( - 273.15^{\circ}\text{C}\approx - 273^{\circ}\text{C}\), but the option says "\(-273^{\circ}\text{C}\) on the Celsius scale" (close, but let's check Kelvin).
• For Rankine: The formula to convert Kelvin to Rankine is \( R = 1.8K \). At \( K = 0 \), \( R=0\,\text{R}\), so \( 220^{\circ}\text{R}\) is incorrect.

The Kelvin scale defines absolute zero as \( 0\,\text{K} \), so the correct option is the one with \( 0\,\text{K} \) on the Kelvin scale.

Answer:

C. \( 0\text{K} \) on the Kelvin scale (assuming the orange option with the white circle is labeled as C, but based on the content, the correct option is the one stating "0K on the Kelvin scale")
