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.
Best Answer: Steam is usually 100 degrees celsius. If you took chemistry, you will know that there is no temperature change during a phase change. However after the phase change has occurred the steam can keep increasing in temperature. that is why your hand will burn quicker and more severely in steam than in boiling water.
