Answer:
20 K
Explanation:
It is given that,
The change in temperature is 20 C.
We need to find the change in thermodynamic temperature.
If teperauture T₁ = 0° C = 0+273 = 273 K
T₂ = 20° C = 20 + 273 = 293 K
The change in temperature,
So, the change in temperature of 20°C is equivalent to 20 K.
"0.049 W" is the correct answer.
According to the given question,
As we know,
⇒
