Solution: Let us take C1 = 30o C and C2 = 35o We know that the expression for relating celsius and faranheit degree is given by: F = 9/5C + 32 Making use of the formula aove, we can write: $...
Solution: Let us take F1 = 86o F and F2 = 95o We know that the Faranhiet and Celsius relation is given by: F = 9/5C + 32 F1 = 9/5 C1 + 32 F1 – 32 = 9/5 C1 C1 = 5/9 (F1 – 32) = 5/9 (86 – 32) C1 =...
