Question

If 27 °C+x=300 K, then the value of x is

• A. 0 K
• B. 327 K
• C. 273 K
• D. 300 K

Answer 1

The Correct Option is A

We are given that $27^\circ C + x = 300K$. 

We know that $K = C + 273.15$. So, $27^\circ C = 27 + 273.15 = 300.15 K$. 

Then we have $300.15 + x = 300$ $x = 300 - 300.15 = -0.15 K$ 

$K = C + 273$. 

Then $27^\circ C = 27 + 273 = 300 K$. 

So, $300 K + x = 300 K$. 

Therefore, $x = 300 K - 300 K = 0 K$.
