1) What is the saturation vapor pressure
based on the graph, 23.4mb
2) What is the vapor pressure in the art gallery when the relative humidity dropped to 269070
RH = (VP/SVP)*100 26 (VP/23.4) *100 = 6.084
3) What was the dewpoint temperature in the art gallery when the relative humidity dropped to 26%?
Td= 68- ((100-26)/5) = 53.2
B)
It increases by 45%
