But it is also extremely toxic and has a relatively high freezing point of +1C. It is also unstable, an inherent property of any substance with a positive enthalpy of formation. Nitrous oxide can be used as an oxidizer with various fuels; it is popular mainly in hybrid rockets. It is far less toxic than hydrazine and has a much lower boiling ...
A Houston dentist led cops on a brief chase Saturday before getting nabbed him with more than 100 canisters of nitrous oxide, or laughing gas, stashed inside his car — and admitted he likes ...

White House officials will take more time to review a sweeping plan from U.S. health regulators to ban menthol cigarettes, an unexpected delay that anti-tobacco groups fear could scuttle the long ...
The relative activity of a species i, denoted a i, is defined [4] [5] as: = where μ i is the (molar) chemical potential of the species i under the conditions of interest, μ o i is the (molar) chemical potential of that species under some defined set of standard conditions, R is the gas constant, T is the thermodynamic temperature and e is the exponential constant.
A pulmonologist and the American Lung Association are among those raising health concerns about heated tobacco products.
