沸腾的水停止加热后，会停止沸腾，这说明水沸腾时要吸热；在瓶底浇冷水后，瓶内温度降低，水蒸气液化，气体压强减小，因为水的沸点会随气压的减小而降低，因此，水会重新沸腾起来．

故答案为：水的沸点会随气压的减小而降，
绝对真。age_type=1/ssid=0/uid=0/pu=usm%400%2Csz%401320_1001%2Cta%40iphone_2_4.1_3_534/baiduid=A5CD17803051D1C6FDEC50C564B51CFE/w=0_10_%E8%B6%B3%E4%BA%A4%E8%A7%86%E9%A2%91oootube/t=iphone/l=3/tc?fm=alop&m=8&ntc=1&srd=1&asres=1&title=%25u56FD%25u4EA7%25u8DB3%25u4EA4-%25u89C6%25u9891%2F%25u6700%25u540E%25u7684%40OOO-Tube&dict=32&tch=124.0.0.0.0.0%252C124.67.271.117.0.0%252C124.77.271.114.0.0&eqid=1dd159be1c9df00010000002577ce61b&wd=&clk_info=%257B%2522srcid%2522%253A%2522www_normal%2522%252C%2522tplname%2522%253A%2522www_normal%2522%252C%2522t%2522%253A1467803171268%252C%2522xpath%2522%253A%2522div-a-h3-em3%2522%257D&tcid=iqas40f0&bdenc=1&nsrc=IlPT2AEptyoA_yixCFOxXnANedT62v3IGRmO_DpF1Dv5nk_qva02Cd9nYT7qAp7ZIlGwdoTQshgYwk0cQDNxmgV2muwrcy-zijvwdcbtdhPs
