如图所示的玻璃管ABCD，在水平段CD内有一段水银柱，玻璃管截面半径相比其长度可忽略，B端弯曲部分长度可忽略。初始时数据如图，环境温度300K。现保持CD水平，将玻璃管缓慢竖直向下插入大水银槽中，使A端在水银面下5cm。已知大气压75cmHg。

（1）在插入水银槽后，玻璃管保持静止，缓慢降低温度，降低到多少时，水平段水银柱回到初始位置；

（2）在（1）的前提下，继续缓慢降低温度，降低到多少时，水平段水银柱刚好全部进入竖直管内。

At the beginning of my 8:00 a.m. class one Monday at UNLV（拉斯维加斯内华达大学）, I cheerfully asked my students how their weekend had been. One young man said that his weekend had not been very good. The young man then proceeded to ask me why I always seemed to be so cheerful.

His question reminded me of something I’d read somewhere before: “Every morning when you get up, you have a choice about how you want to approach life that day,” I said to the young man. “I choose to be cheerful.”

“Let me give you an example,” I continued. “In addition to teaching here at UNLV, I also teach out at the community college in Henderson. One day a few weeks ago I drove to Henderson. I exited the freeway and turned onto College Drive. But just then my car died. I tried to start it again, but the engine wouldn’t turn over. So I put my flashers on, grabbed my books, and marched down the road to the college.”

“As soon as I got there, the secretary in the Provost’s office asked me what had happened. ‘This is my lucky day’, I replied, smiling.”

“Your car breaks down and today is your lucky day?” She was puzzled, “What do you mean?”

“I live seventeen miles from here. I replied. My car could have broken down anywhere along the freeway. It didn’t. Instead, it broke down in the perfect place: off the freeway, within walking distance of here. I’m still able to teach my class, and I’ve been able to arrange for the tow truck to meet me after class. If my car was meant to break down today, it couldn’t have been arranged in a more convenient fashion.”
