Changes in the function of the central nervous system have been observed at concentrations of 20–25 mg/m 3. There are also reports of harms to health at 10 mg/m 3 , for exposures of 10–15 years, but the lack of good data on past exposure levels make the association of these harms with concentrations of 10 mg/m 3 findings uncertain.
Paraffin wax (or petroleum wax) is a soft colorless solid derived from petroleum, coal, or oil shale that consists of a mixture of hydrocarbon molecules containing between 20 and 40 carbon atoms. It is solid at room temperature and begins to melt above approximately 37 °C (99 °F), [ 2 ] and its boiling point is above 370 °C (698 °F). [ 2 ]

A typical Campden tablet contains 0.44 g of sodium metabisulfite, plus filler; eight of these are equivalent to one-half level teaspoon (2.5 mL) of sodium metabisulfite. Other Campden tablet formulations use potassium metabisulfite. Both are referred to, interchangeably, as sulfites, and the 'bi' can be found as 'di'.
The density of liquid propane at 25 °C (77 °F) is 0.493 g/cm 3, which is equivalent to 4.11 pounds per U.S. liquid gallon or 493 g/L. Propane expands at 1.5% per 10 °F. Thus, liquid propane has a density of approximately 4.2 pounds per gallon (504 g/L) at 60 °F (15.6 °C). [30]
