If the pressure on the surface of water in the liquid stato is 47 kPa, the water will boil at
A) 0.0°C
B) 40°C
C) 80°C
D) 101.3°C

The water will boil at C) 80°C

Given

Vapour pressure of water = 47 kPa

Required

Boiling point of water

Solution

We can use the Clausius-Clapeyron equation :

Vapour pressure of water at boiling point 100°C=101.325 kPa

ΔH vap for water at 100°C=40657 J/mol

R = 8.314 J/mol K

T₁=boiling point of water at 101.325 kPa = 100+273=373 K

Input given values :

14 days is the half-life of phosphorus-32

sorry i was late, but i don't know what assignment your talking about, i'm in flvs as well, im in earth space science. but u are behind pace bc every class should be in the 3's or 4'
