It depends a bit on the context, whether she meant simply to explain that nitrogen is an element found in the environment, or whether the listener is meant to extrapolate from this statement that liquid nitrogen is safe. Since she could make the same claim and cook with arsenic, the purpose of the statement is rhetorically cloudy, I would agree, but I think most non-chemists would equate "natural" with "safe"<br /><br />And as chemists we know that states matter, mercury vapor has hazards that mercury liquid does not.Michellehttps://www.blogger.com/profile/12617476463347663364noreply@blogger.comtag:blogger.com,1999:blog-12261589.post-44145509360702095332013-04-26T15:22:17.949-04:002013-04-26T15:22:17.949-04:00I suspect that Robyn Sue Fisher is referring to th...I suspect that Robyn Sue Fisher is referring to the material, not its state.
