Question

Find the value of \(-197^\circ C\) temperature in Kelvin.

• A. 47 K
• B. 76 K
• C. 470 K
• D. 760 K

Hint:

Always add 273 (or 273.15 for precision) to Celsius to get Kelvin. Negative Celsius values still yield positive Kelvin values as long as they are above absolute zero (\(-273.15^\circ C\)).

Answer 1

The Correct Option is B

Step 1: Recall the scale link.
To go from Celsius to kelvin we just add about $273$.

Step 2: Substitute.
\[ T = -197 + 273. \]

Step 3: Add.
This gives $76\ \text{K}$ (using $273.15$ gives $76.15$, which rounds the same way).

Step 4: State it.
\[ \boxed{76\ \text{K}} \]
