Answer
(a) The temperature is $-196~^{\circ}C$
(b) The temperature is $-321^{\circ}F$
Work Step by Step
(a) We can convert the temperature to $^{\circ}C$:
$C = K-273$
$C = 77-273$
$C = -196$
The temperature is $-196~^{\circ}C$
(b) We can convert the temperature to $^{\circ}F$:
$F = \frac{9}{5}C+32$
$F = \frac{9}{5}(-196)+32$
$F = -321$
The temperature is $-321^{\circ}F$
