This warming is in addition to carbon dioxide's better-known effect as a heat-trapping greenhouse gas. For scientists trying to predict global climate change in the coming century, the study underscores the importance of including plants in their climate models.
It is a physical change. All phase changes are physical, not chemical. The chemical composition of water does not change when it changes from a liquid to a gas, or for that ma â¦ tter, to a solid.
You can't add any more energy (heat) to that molecule while in the liquid form because once it reaches that temperature it changes state. When you are looking at a pot of water heating on the stove, it doesn't just instantly flash in to steam when it reaches a certain temperature.o anything above that temperature will cause the water will change to a vapor (steam). That's why if you add heat to â¦ boiling water you won't see a rise in temperature of the liquid.
