Answer
Melting point= $801^{\circ}\,C=1474^{\circ}F$
Boiling point= $1413^{\circ}C=2575^{\circ}F$
Work Step by Step
We find:
Melting point= $1074\,K= (1074-273)^{\circ}C=801^{\circ}\,C$
$=[(801\times\frac{9}{5})+32]^{\circ}F=1474^{\circ}F$
Boiling point= 1686 K= $(1686-273)^{\circ}C=1413^{\circ}C$
$=[(1413\times\frac{9}{5})+32]^{\circ}F=2575^{\circ}F$
