一支刻度位置不准确但刻度均匀的温度计的示数在沸水中为99℃在冰水混合物中示数为4℃，如果当时室内温度是20℃，则此温度计测量时示数为______，当被测物体温度为______时，此温度计的示数与实际温度相同．
按照摄氏温度的规定，冰水混合物的温度为0℃，1个标准大气压下沸水的温度为100℃，
题中的温度计4℃刻线对应的实际温度是0℃，99℃刻线对应的实际温度为100℃，4℃刻线和99℃刻线之间共有100个小格，表示的实际温度为100℃，每个小格表示的实际温度为
℃=100 99-4
℃；20 19
如果当时室内温度是20℃，则此温度计测量时示数4℃+
℃=23℃；20 20 19
设液体的实际温度为t，则：
℃=20 19 t t-4℃
解得t=80℃．
故答案为：23℃；80℃．
