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.
This is the amount of heatrequired to convert boiling water to steam. This amount of heat is large compared to that requiredto make water hot. For example, it takes 80 calories to make 1 liter of water boil, but 540 caloriesto convert that boiling water to steam. Therefore, steam at 100â¦ C has almost seven times moreheat than boiling water. Steam is able to penetrate objects with cooler temperatures because oncethe steam contacts a cooler surface, it immediately condenses to water, producing a concomitant1,870 fold decrease in steam volume.
