31. It is a method for relating the reactant liquid flow rate to the reactor volume at a standard temperature . 32. *A human weighing 200lbs occupies about 89 liters of space, about four moles of gas at standard temperature and pressure. 33. Where T is the mean day temperature in Kelvin and DTS represents the number of days transformed to standard temperature . 34. In the case of solar cells at standard temperature and pressure, this loss accounts for about 7 % of the power. 35. At standard temperature and pressure, hydrogen is a colorless, odorless, nonmetallic, tasteless, highly diatomic gas with the molecular formula H 2. 36. In the United States, the standard temperature is most commonly defined as 60 �F or 70 �F, but again, not always. 37. While its appearance at standard temperature and pressure is unknown, it can present as a white solid, which is thermally stable below. 38. It consists of one central phosphorus atom surrounded by four oxygen atoms in a soluble in water at standard temperature and pressure. 39. These values are true only for a completely reversible reaction at standard temperature and pressure ( 1 bar and 25 �C ). 40. At standard temperature and pressure, it has the ammonia / bleach odor common to amines and is soluble in almost all organic solvents.
