Question

С помощью уличного термометра измерьте температуру сначала на солнечной стороне дома затем на теневой.Объясните почему различаются показания термометра

Answer 1

На солнечном свету, термометр ловит солнечные лучи в инфракрасном спектре, которые его нагревают, что дает неверные показания. В тени, инфракрасные лучи рассеяны, что дает более точное показание.

Answer 2

Measuring Temperature on the Sunny and Shady Sides of a House

To measure the temperature on the sunny and shady sides of a house using an outdoor thermometer, follow these steps:

1. Place the thermometer on the sunny side of the house, making sure it is not in direct sunlight. Direct sunlight can affect the accuracy of the temperature reading. 2. Wait for a few minutes to allow the thermometer to adjust to the ambient temperature. 3. Take note of the temperature reading displayed on the thermometer. 4. Move the thermometer to the shady side of the house, again ensuring it is not in direct sunlight. 5. Wait for a few minutes for the thermometer to adjust to the new ambient temperature. 6. Record the temperature reading displayed on the thermometer.

Explanation for the Difference in Thermometer Readings

The difference in temperature readings between the sunny and shady sides of a house can be attributed to several factors:

1. Solar Radiation: The sunny side of the house receives direct sunlight, which leads to the absorption of solar radiation. This absorption increases the temperature on the sunny side, resulting in a higher temperature reading on the thermometer. 2. Shade and Insulation: The shady side of the house, on the other hand, is shielded from direct sunlight and receives less solar radiation. Additionally, the shade provided by nearby trees or buildings can further reduce the temperature. Furthermore, the insulation properties of the house may also play a role in maintaining a cooler temperature on the shady side. 3. Air Circulation: The movement of air around the house can also contribute to temperature differences. On the sunny side, warm air rises, creating a convection current that can increase the temperature. On the shady side, cooler air may be present due to the absence of direct sunlight and the presence of shade, resulting in a lower temperature reading on the thermometer.

It is important to note that the temperature difference between the sunny and shady sides of a house can vary depending on factors such as the time of day, weather conditions, and the specific characteristics of the house and its surroundings.

Conclusion

By measuring the temperature on the sunny and shady sides of a house using an outdoor thermometer, you can observe the temperature difference caused by solar radiation, shade, insulation, and air circulation. This simple experiment can help you understand how different factors can influence temperature variations in different areas of your surroundings.

Please note that the specific temperature readings and differences will vary based on the location, time of day, and other environmental factors.
