唔係考人.....係我唔識............= =
點以邏輯慨念去思考??.......可以詳細d嗎??........... 人唔識你唔識...你用英文黎話唔識!!
melting ice = 0.1degrees or above
over boiling water = 100degrees
child common sense
base on it,
true thermometer 0degrees to 100degrees =100-0 =100dscale
faulty thermometer 10degrees to 900degrees =90-10 =80scale
=100/80 =1.25
.'. 1 scale of faulty thermometer =1.25 scale of true thermometer
.'. 40 X 1.25 =50 scale in true thermometer and = 50'C
It just a primary mathematics using question(文字題),can't construe that to be a scientific question
