Heat Generated by the Combustionof Hydrogen.—The flame of hydrogen, althoughslightly luminous, produces a great degree of heat. Whenthe combustion is assisted by oxygen gas, the heat gen- QuESTiONS.—What other substances possess similar properties ? When a jet of hydro-gen is thrown upon spongy platinum, -what ensues ? What is the construction of Dohe-reiners lamp ? When hydrogen is burned from a jet in a tube, what phenomenon is no-ticed ? What is said of the heating effects of the hydrogen flame ?.
