Question 1 of 30

In a smart home environment, a device is using the Constrained Application Protocol (CoAP) to communicate with a central server. The device sends a request to the server to retrieve the current temperature reading from a sensor. The server responds with a payload containing the temperature in Celsius. If the temperature is recorded as 25°C, and the device needs to convert this reading to Fahrenheit for display purposes, which of the following conversion formulas should the device use to accurately convert the temperature?

\( F = \frac{9}{5}C + 32 \)

\( F = C - 32 \)

\( F = \frac{5}{9}(C - 32) \)

\( F = 32C + 32 \)
