Answer
a) $518.15\, K$
b) $-247.95^{\circ}C$
c) $-43.6^{\circ}F$
d) $316.48\, K$
Work Step by Step
a) $245^{\circ} \, C=(245+273.15) \, K=518.15\,K$
b) $25.2\, K=(25.2-273.15)^{\circ} C=-247.95^{\circ}C$
c) $-42.0^{\circ}\, C=[(-42.0\times\frac{9}{5})+32]^{\circ}\,F$
$=-43.6^{\circ}F$
d) $110.0^{\circ}F=[(110.0-32)\times\frac{5}{9}]^{\circ}C$
$=43.33^{\circ}C=(43.33+273.15) K$
$=316.48\, K$
