Is it possible to boil 75i .ogax po;gwate,8yu.nyu 1g2flsm e9cr 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.
