Question

Convert $5^{0}F$ according to (i) Celsius scale, and (ii) Kelvin scale.

• A. (i) $-{15}^{0}C$
  (ii) $258K$
• B. (i) $-17{}^{0}C$
  (ii) $288K$
• C. (i) $-{15}^{0}C$
  (ii) $-258K$
• D. (i) ${20}^{0}C$
  (ii) $237K$

Answer 1

The correct option is A (i) $-{15}^{0}C$

(ii) $258K$

1. $C=\frac{5}{9}\times (F-32)$

Putting $F=5$, we get $C=-{15}^{0}C$

2. $K=\frac{5}{9}\times (F-32)+273$

Putting $F=5$, we get $K=258K$
