填空题

欧洲核子研究中心( CERN)的大型强子对撞机LHC 于2008年9月10 日正式启动。强子对撞机LHC位于法国 和瑞士边境100米深处的环形隧道中,是目前世界上最大的粒子加速器,也被称为“时间机器”,其目的是要解开宇宙形 成之谜,实验模拟演绎宇宙在137亿年前发生大爆炸之初的 原始情景。

(1)9月19 日欧洲强子对撞机发生严重氦泄漏事故而熄火, 有将近一吨液态氦在隧道里发生泄漏,使隧道的真空失效,修复时间至少需要两个月。其中使用的液氦质量占全世界年产量的10%。液氦的化学式为_________,由于液氦的沸点极低,在核技术中可用作_______。

(2)常温下,氦气的化学性质________(填“很”或“不”)活泼,其密度为0. 19g/L,可用于填充飞船和大型气球。还可用于___________、____________(至少说出 两点)。
