First, lift is proportional to mass-air flow over a curved surface.

A curved surface has nothing to do with lift.

Of course it does, the propeller produces more thrust when the air is
colder ( A propeller is a curved surface )

Now, back to the orginal question, if the engine is maintained at a
constant rpm at a some cold and hot temperatures, it will burn more
fuel at the colder temperature, but it will also produce more thrust.
So to get the same thrust, you would throttle back and almost the same
fuel burn with less rpm.
