Which factor causes the surface of Lake Ontario to cool at a slower rate than the surface of the land along the shore of the lake?
Sunlight passes through the top layers of the lake water.
Water vapor cools the lake as it condenses.
Lake water has a higher specific heat than land.
Evaporating water releases more heat into the lake than into the land.
In heat transfer, heat always moves from the (a) object to the (b) object.
hot
cold
wet
dry
