Answer:Today, rapidly increasing air pollution in developing countries, has imposed a serious threat on public health and the environment. Box model is among those techniques that are used for predicting of air quality.
The smoke from a cigarette will not go outside the room unless the room has high pressure compared to the outside pressure.so if you want to smoke then you should smoke near the window .and in order to let that smoke out ,you should smoke it close to the upper part of the window .since warm air is lghter than cold air ,warm air will go out from the upper part of window and cold air will come in through the bottom part.
hence if at all you want to smoke always smoke near the small area of the window where the warm air is going out.
and if each person will reduce the smoking of cigerattes per hour then that would automatically lead to reduce in the concentration of smoke which is also healthy for the person.
Step-by-step explanation:
The passage discusses two main points related to air pollution and smoking near windows.
Firstly, it highlights the issue of rapidly increasing air pollution in developing countries and its detrimental effects on public health and the environment. This indicates that air pollution is a serious threat that needs to be addressed. The passage mentions the use of the box model as one of the techniques employed to predict air quality, implying that understanding and predicting air pollution is crucial for taking appropriate measures.
Secondly, the passage focuses on the smoke from a cigarette and its behavior inside a room. It explains that the smoke will not leave the room unless the room has higher pressure compared to the outside. To allow the smoke to exit, the suggestion is to smoke near a window and specifically close to the upper part of the window. This is because warm air, being lighter than cold air, tends to rise and escape through the upper part of the window. This creates a flow of air, allowing fresh, colder air to enter through the bottom part of the window.
Based on this information, the passage recommends smoking near the small area of the window where the warm air is going out. By doing so, the smoke is more likely to be directed out of the room, reducing its concentration and minimizing its impact on the person and the indoor environment.
Additionally, the passage suggests that if each person reduces the number of cigarettes smoked per hour, it would lead to a decrease in the concentration of smoke. This reduction in smoke concentration is considered beneficial for the health of the individual.
Overall, the passage highlights the importance of understanding air pollution, suggests a method to minimize smoke concentration while smoking near windows, and emphasizes the positive impact of reducing cigarette smoking on personal health.
