Is it possible to boikp te lb:o1l wm)ryd.t4l0p2 ,l watec,ufiin1 wi+3y kz7d, iu :fd9r at room temperature (20 $^{\circ} $ C) without heating it? Explain.
参考答案: Liquids boil when their saturated vapor pressure
equals the external pressure. For water,
from Table 13-3, the saturated vapor pressure of water at 20 $^{\circ} $ C is
about 0.023 atm. So if the external
pressure is lowered to that level (about 2.3% of normal air pressure), the
water will boil.
