Physics problems in the second day of junior high school. There is a thermometer with even scale but inaccurate reading. It shows 4 C in ice-water mixture and 96°C in boiling water.
The index of ice-water mixture is 4℃, which is equivalent to 0℃ of actual temperature, and that of boiling water is 96℃, which is equivalent to 100℃ of actual temperature, so there are 92 squares between 4℃ and 96℃, so each 1 square is equivalent to actual 100/92℃ and 29℃.
