Use the table of temperatures measured in two areas of a house to answer the question.
Area | Temperature
Downstairs | 22
Upstairs | 26
Which statement best explains the temperature difference?
(1 point)
Energy from the cooler air is transferred upstairs.
The cooler air downstairs loses energy to the environment.
Warm air rises by convection to the upstairs.
Energy is transferred between the areas when the molecules touch.
To determine which statement best explains the temperature difference between the downstairs and upstairs of a house, we can analyze the information provided.
From the table, we observe that the temperature downstairs is 22 degrees, while upstairs, it is 26 degrees.
Now let's evaluate each statement to see which one is the most accurate:
1. Energy from the cooler air is transferred upstairs: This statement suggests that the colder air downstairs is transferring its energy to the warmer air upstairs, resulting in a temperature difference. However, according to the information provided, there is no mention of any specific energy transfer between the areas.
2. The cooler air downstairs loses energy to the environment: This statement acknowledges that the cooler air downstairs loses energy. While this energy loss may contribute to the temperature difference, we cannot confirm if it is the primary reason solely based on the given data.
3. Warm air rises by convection to the upstairs: This statement suggests that warm air rising through convection is responsible for the temperature difference. Since warmer air typically rises, it could explain the higher temperature recorded upstairs compared to downstairs. This statement aligns with the given data, as the higher temperature is recorded upstairs.
4. Energy is transferred between the areas when the molecules touch: This statement suggests that energy transfer occurs when molecules come into contact with each other. Although this is true and can contribute to heat transfer, it does not provide a direct explanation for the temperature difference between the downstairs and upstairs.
Based on the given information, the statement that best explains the temperature difference between the downstairs and upstairs is: "Warm air rises by convection to the upstairs." This statement aligns with the observation that the temperature is higher upstairs and is consistent with the natural movement of warm air. However, it is important to note that additional factors, such as heating systems or insulation, could also contribute to the temperature difference.
