Question

Calculate the value of the following expression in celsius scale.

$\frac{(298K\times {50}^{o}C)}{(275K+3^{o}C)}$

• A. ${300}^{o}C$
• B. ${250}^{o}C$
• C. ${200}^{o}C$
• D. ${350}^{o}C$

Answer 1

The correct option is B ${250}^{o}C$

To convert from Kelvin scale to Celsius scale, subtract 273 from Kelvin scale.

$298K={25}^{o}C,275K=2^{o}C$ therefore on calculating $\frac{(25\times 50)}{5}={250}^{o}C$
