Question

Какой процесс называется изотермическим? Как меняется влажность воздуха в помещении, если разница показе термометров психометра уменьшается?

Answer 1

1) процесс происходящий при постоянной температуре.

2) относительная влажность повышается, когда равны, становится 100%.

Answer 2

Isotermic Process

An isotermic process is a thermodynamic process in which the temperature of a system remains constant throughout the process. In other words, the system undergoes a change in its state while maintaining a constant temperature. This means that the heat added to or removed from the system is balanced by an equal amount of work done by or on the system, resulting in no change in temperature.

Change in Humidity with Decreasing Difference in Psychrometer Thermometer Readings

The humidity of the air in a room is affected by various factors, including temperature and the amount of moisture present in the air. The difference in readings between two thermometers, one dry and the other wet (known as a psychrometer), is used to determine the relative humidity of the air.

When the difference in the psychrometer thermometer readings decreases, it indicates that the air is becoming more saturated with moisture. This means that the relative humidity is increasing. As the air becomes more saturated, it reaches a point where it can no longer hold as much moisture, resulting in condensation. This is often observed as dew forming on surfaces.

In summary, when the difference in the psychrometer thermometer readings decreases, it indicates an increase in relative humidity and a higher likelihood of condensation occurring in the room.

Please note that the specific numerical relationship between the difference in psychrometer thermometer readings and the change in relative humidity may vary depending on various factors such as the initial conditions and the specific properties of the air in the room.
