**Question Stem / Problem Description:**
1. 在一个密封的玻璃罩内放置两根长短不同的点燃的蜡烛,一段时间后,观察哪根蜡烛先熄灭。
(Place two lit candles of different lengths inside a sealed glass cover. After a period, observe which candle extinguishes first.)
2. 有同学认为蜡烛熄灭的顺序与玻璃罩的大小有关。如果玻璃罩的体积大一些,同时玻璃罩再高一些,可能结果就不一样。不妨试一试,并和同学们交流结果。
(Some classmates believe that the order in which the candles extinguish is related to the size of the glass cover. If the glass cover is larger in volume and also taller, the result might be different. You might as well try it and discuss the results with your classmates.)
