Question

Water vapor condensation on the outside of a water bottle. Endothermic or exothermic and why?

Answer 1

It is endothermic reaction. Because water vapour must absorb heat to increase their kinetic energy so that they can condense...

Answer 2

Explanation:

Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green.
