Question

The reading on a clinical thermometer is $32{}^{\circ }C$. What will be the equivalent value in the kelvin and the fahrenheit scales, respectively?

• A. $303K\&303{}^{\circ }F$
• B. $305K\&89.6{}^{\circ }F$
• C. $303K\&89.6{}^{\circ }F$
• D. $303K\&305{}^{\circ }F$

Answer 1

The correct option is B $305K\&89.6{}^{\circ }F$

Given:
$T_c=32{}^{\circ }C$

In kelvin scale, temperature is given by:
$T_K=T_c+273$
$T_K=32+273=305{}^{\circ }C$

In fahrenheit scale, temperature is given by:
$T_F=\frac{5}{9}{T}_c+32$
$T_F=\frac{5}{9}\times 32+32$
$T_F=89.6{}^{\circ }F$
