열역학 제1법칙의 에너지보존법칙에 의하면 시스템으로 들어온 에너지는 들어온 만큼 나가야 한다. 그러나 현재 지구는 태양복사에너지를 받은 만큼 이산화탄소의 온실가스 때문에 내보내지 못함. 때문에 지구의 온도가 점점 올라가고 있다. 지구 온난

Last concern is depleted uranium (DU) projectiles. Depleted uranium is very dense and is used in projectiles designed to pierce armour, reinforced bunkers and other similar targets. Depleted uranium projectiles create fragments and dust, which release uranium oxide into the air. Estimates of the amount of depleted uranium used by allied forces in the first Gulf War range from 290 ton
