A temp change of 20 degrees C corresponds to a temp change of
68degrees F
i got this one wrong? whats up with that???

Water freezes at 32 degrees F= 0 degrees C
Water boils at 212 degrees F= 100 degrees C
so that 212-32= 190 degrees F spans as much as 100 degrees C so each degree C corresponds to 190/100= 1.9 degrees F.
A change of 20 degrees C corresponds to a change of 20(1.9)= 38 degrees F.
(Or, you could have argued that 20 degrees C is 1/5 of the way from freezing to boiling and so corresponds to (212-32)/5= 190/5= 38 degrees F.
(Oh, by the way, a temperature of 20 degrees C is 70 degrees F, not 68. The general formula is F= 1.9C+ 32.
