Question

Part A: The water in the spray bottle has a temperature of 25 C. The thermometer in the terrarium reads 30 C, and a thermometer in the room where the terrarium is located reads 25 C. The temperature outdoors is 40 C.
What is the temperature of the water vapor inside the terrarium? Select the correct temperature.

Answer 1

To determine the temperature of the water vapor inside the terrarium, we need to consider the context of the temperatures provided:

1. The water in the spray bottle is at 25°C.
2. The thermometer in the terrarium reads 30°C.
3. The room temperature is 25°C.
4. The outdoor temperature is 40°C.

The temperature of the water vapor inside the terrarium is influenced by the temperature of the air in the terrarium, which is indicated by the 30°C reading on the thermometer. The water vapor will generally be at or near the temperature of the air, assuming the system has reached equilibrium.

Given that the thermometers measure air temperature, and the air temperature inside the terrarium is 30°C, we can conclude that the temperature of the water vapor will also be around 30°C.

Answer: 30°C
