Sure, let's convert the given temperatures from the Kelvin scale to the Celsius scale.
To perform this conversion, we use the formula:
[tex]\[ \text{Temperature in Celsius} = \text{Temperature in Kelvin} - 273.15 \][/tex]
Let's apply this formula to each given temperature.
a) 293 K
[tex]\[
\text{Temperature in Celsius} = 293 \, K - 273.15
\][/tex]
[tex]\[
\text{Temperature in Celsius} = 19.85 \, ^\circ C
\][/tex]
So, 293 K is equivalent to [tex]\( 19.85 \, ^\circ C \)[/tex].
b) 470 K
[tex]\[
\text{Temperature in Celsius} = 470 \, K - 273.15
\][/tex]
[tex]\[
\text{Temperature in Celsius} = 196.85 \, ^\circ C
\][/tex]
So, 470 K is equivalent to [tex]\( 196.85 \, ^\circ C \)[/tex].
