Answer

Here, First we convert temperature from degree F to degree R to solve for temperature in degree R T( degree F) = T( degree R) – 459.67 --> T( degree R) = T( degree F) + 459.67 $T_{oven}$ ( degree R) = 350 degree F + 459.67 = 809.67 degree R Next to solve for temperature in K we know , T( degree R) = 1.8T(K) → T(K) = T( degree R)/1.8 $T_{oven}$ (K) = 809.67 degree R/1.8 = 449.82 K Finally, to solve for temperature in degree C we use T( degree C) = T(K) – 273.15 $T_{oven}$ ( degree C) = 449.82 K – 273.15 = 176.67 degree C
