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.
Under normal circumstances, when you boil water in everyday life, the steam you make from heating water to its boiling point will be the exact same temperature as the water that is boiling. Note: this does not mean the energy content is the same. Steam has a LOT more energy than water at the same temperature. For example, steam at 100Â°C contains more than six times the amount of energy than water boiling at 100Â°C (see here: Saturated Steam Tables ). The answer to your question is then: yes, and no.
