What happens to molecular energy(heat) in water when water vapor becomes a liquid? 1) Water vapor gives up heat energy.
2) Water vapor retains the same heat energy.
3) Water vapor absorbs heat energy.
4) As water's mass increases it absorbs energy.

1 is your answer i believe

Explanation:

As the molecules lose heat, they lose energy and slow down. They move closer to other gas molecules. Finally these molecules collect together to form a liquid.

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.

weathering - colorado river carves land in arizona to form the grand canyon. cracks form in a sandstone wall surrounding a house. a marble statue near the science museum is changing color due to rainfall

erosion - after a rainstorm, soil and rock piees litter the roadways. the sand dunes in the sahara desert are changing shape.

here's your answer.
