一、佯谬的提出有这样一个气体状态变化问题:若有一根粗细均匀一端封闭,开口向上竖直(?)玻璃管,管长为L=100厘米,用h=20厘米的水银柱封闭了一段气体、气柱长a=50厘米、已知这时的室温T_1=300°K,外界气体压强为p_0=76厘米汞柱,对空气缓慢加热,求:1.当管内气体的温度至多高时水银柱的上端面恰到管口。2.管内气体温度至少为多高时,可使管中的水银从管内全部溢出.
First, the helium’s proposal has such a problem of gas state change: if a uniform thickness is closed at one end, the glass tube is opened upright (?), the tube length is L=100 cm, and it is sealed with a mercury column of h=20 cm. A section of gas, air column length a = 50 cm, known room temperature T_1 = 300 °K, outside gas pressure p_0 = 76 cm Hg, slowly heating the air, seeking: 1. When the gas temperature inside the tube at most When the upper end of the mercury column just to the nozzle. 2. When the gas temperature in the tube is at least high, the mercury in the tube will overflow from the tube.
