In which case would you revise a hypothesis?
a. when you have no prior knowledge of a subject
b. when you do not have enough data to make a graph
c. when your experiment design does not work
d. when experimental results do not support the original hypothesis

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
