The wall surface is typically around 5-10 degrees colder than the air in close proximity. This is because the wall absorbs and retains the cold temperature from the surrounding environment, while the air is more influenced by immediate changes in temperature. This temperature difference can vary depending on factors such as insulation, material of the wall, and the outdoor climate. **

The ability of a chief to dismiss a deputy chief would depend on the specific policies and procedures of the organization or department. In some cases, the chief may have the authority to dismiss a deputy chief, especially if the deputy chief is serving at the pleasure of the chief. However, in other cases, there may be employment contracts or civil service regulations that govern the dismissal of deputy chiefs, which could limit the chief's ability to dismiss them unilaterally. Ultimately, the specific circumstances and governing rules would determine whether the chief can simply dismiss a deputy chief. **

Proximity sensors are devices that can detect the presence or absence of an object within a certain distance without any physical contact. They work by emitting an electromagnetic field or a beam of electromagnetic radiation and then detecting changes in the field or beam caused by the presence of an object. Proximity sensors are commonly used in various applications such as smartphones, automotive systems, industrial automation, and robotics to detect the presence of objects, measure distances, and trigger actions based on proximity. **

A proximity sensor is a type of sensor that is able to detect the presence of nearby objects without physical contact. It works by emitting an electromagnetic field or beam of radiation and then detecting changes in the field or return signal. Proximity sensors are commonly used in electronic devices, such as smartphones, to detect when an object is close to the screen and adjust the display accordingly. They are also used in industrial applications for object detection and automated systems. **
