Soal diatas dapat diselesaikan dengan perbandingan 2 termometer.

fraction numerator T subscript x minus T subscript 0 x end subscript over denominator T subscript t x end subscript minus T subscript 0 x end subscript end fraction equals fraction numerator T subscript c minus T subscript 0 c end subscript over denominator T subscript t c end subscript minus T subscript 0 c end subscript end fraction fraction numerator T subscript x minus left parenthesis negative 20 right parenthesis over denominator 180 minus left parenthesis negative 20 right parenthesis end fraction space equals fraction numerator 40 minus 0 over denominator 100 minus 0 end fraction fraction numerator T subscript x plus 20 over denominator 200 end fraction equals 40 over 100 fraction numerator T subscript x plus 20 over denominator 2 end fraction equals 40 T subscript x plus 20 equals 80 T subscript x equals 60 degree straight X

Dengan demikian, saat termometer celcius menunjukkan suhu 40oC, maka pada termometer X menunjukkan angka 60oX.space

Penjelasan:

jawaban 60oX
