Question

Suppose that a recipe calls for an oven temperature of 300 °F. Convert this temperature to kelvins.
Express the temperature in kelvins as an integer.

Answer 1

To convert the temperature from Fahrenheit to Kelvin, we can use the following formula:

1. Convert Fahrenheit to Celsius using the formula:
\[
C = \frac{(F - 32) \times 5}{9}
\]

2. Convert Celsius to Kelvin using the formula:
\[
K = C + 273.15
\]

Now we can apply these steps:

1. Convert 300 °F to Celsius:
\[
C = \frac{(300 - 32) \times 5}{9} = \frac{268 \times 5}{9} = \frac{1340}{9} \approx 148.89 \, °C
\]

2. Convert Celsius to Kelvin:
\[
K = 148.89 + 273.15 \approx 422.04 \, K
\]

Now rounding the Kelvin temperature to the nearest integer:
\[
K \approx 422 \, K
\]

Therefore, the temperature of 300 °F is approximately **422 K** when expressed as an integer.
