Laughing Gas (novel) and darling of all American mothers. Joey is also going to have a tooth out, but Joey is going to be operated on by B.K. Burwash, Zizzbaum's rival—they have a common waiting-room—exactly at the same time as Reggie. Presently reporters storm the dentist's practice to take photos of Joey and interview him. Both Reggie and Joey get laughing gas as anaesthetic. When Reggie regains consciousness he finds himself spoken to by B.K. Burwash, and also in the latter's chair. He concludes that there has been a switch in the fourth dimension: Joey's and his souls have changed bodies. Before he
Gas collecting tube the fluid to be investigated. Measure the overall mass formula_2 to calculate the mass of the fluid inside the tube formula_27 yielding the desired mass density formula_12. If the gas is a pure gaseous chemical substance (and not a mixture), with the mass density formula_12, then using the ideal gas law permits to calculate the molar mass formula_30 of the gaseous chemical substance: formula_31 (formula_32 represents the universal gas constant, formula_33 the absolute temperature at which the measurements took place) Gas collecting tube The characterization gas collecting tube describes an oblong gas-tight container with one valve at either end. Usually
