Answer
56.56$^{\circ}$ C
Work Step by Step
For 5.25 cm change temperature rise = 10 F
For 1 cm change temperature rise = $\frac{10}{5.25}$
For 18.5 cm change temperature rise = $10\times\frac{18.5}{5.25}$ = 35.2
Final temperature = 98.6 + 35.2 = 133.8 F
Converting to Celsius = (133.8-32)$\times\frac{5}{9}$ = 56.56
