Answer
a) 138 kPa
b) 33.4 kPa
c) 233 kPa
Work Step by Step
For all of the following problems, we use the following equation:
$\frac{P_1}{P_2}=\frac{T_1}{T_2}$
Thus, we find:
a) $\frac{101}{P_2}=\frac{273}{373} \\ P_2 = 138 \ kPa$
b) $\frac{101}{P_2}=\frac{273}{90.2}\\ P_2 = 33.4 \ kPa$
c) $\frac{P_1}{101}=\frac{630}{273}\\ P_2 = 233 \ kPa$
