HEAT

A faulty thermometer with uniform scale reads 10C and 90C when placed in melting ice and steam over boiling water respectively. What should be the true temperature if the thermometer reads 40C?

以邏輯慨念去思考....

會得出50C係個答案


by logic pondered,


Will work out  50 degree this answer

melting ice             =       0.1degrees or above

over boiling water   =       100degrees

true thermometer     0degrees  to  100degrees    =100-0   =100dscale

faulty thermometer   10degrees  to  900degrees   =90-10   =80scale



[b][size=5]=100/80   =1.25   [/size][/b]


[size=4][color=red][b].'.   1 scale of faulty  thermometer     =1.25 scale of true  thermometer[/b][/color][/size]


[size=4][color=#ff0000][b].'.   40 X 1.25      =50 scale in true  thermometer and = 50'C[/b][/color][/size]







It just a primary mathematics using question(文字題),can't construe that to be a scientific question
