In 1997 Central Ecuador and Peru suffered rainfall more than 10 times normal, which caused flooding, extensive erosion and mudslides with loss of lives, destruction of homes and food supplies.
Use the formula (P1V1)/T1 = (P2V2)/T2
(12.8 * 100)/(-108 + 273) = (.855 * P2)/(22 + 273) Need to convert Celsius into Kelvins
1280/165 = (0.855 * P2)/295
7.755556 = 0.002898 * P2
P2 = 2676.18 kPa
