8. Fog often forms at night as cooler air temperatures cause water vapor to condense.
When fog forms at night, the air temperature remains roughly constant. The
condensation
of water is exothermic.
a. What is the direction of heat transfer:
i. From the water making up the fog to the surrounding air

ii.From the surrounding air to the water making up the fog?
Explain your thinking

b. As the sun sets, the air temperature decreases. But when fog forms, the
temperature remains roughly constant. How can you explain this observation?
