Air will return to the spaces through a combination of natural and mechanical ventilation processes. Natural ventilation can occur through open windows, doors, or vents, allowing fresh air to flow in and stale air to escape. Mechanical systems, such as HVAC units, actively circulate air by drawing in outside air and redistributing it within the space. This ensures a continuous exchange of air, maintaining indoor air quality and comfort.
the air will be in liquid state when its pressure is increased and its temparature is decreased. eg: CNG is highly compressible gas.

Humans impact air quality primarily through emissions from vehicles, industrial activities, and the burning of fossil fuels, which release pollutants like carbon monoxide, nitrogen oxides, and particulate matter into the atmosphere. Deforestation and agricultural practices, such as the use of fertilizers and pesticides, also contribute to air pollution. Additionally, urbanization increases the concentration of pollutants, while inadequate waste management can lead to the release of harmful gases. These activities collectively degrade air quality, posing significant health risks and contributing to climate change.
Air quality standards are designed to protect the population. They ensure that people have clean air to breathe.

When a state fails to meet air quality standards, it can face penalties such as loss of federal funding, increased regulatory oversight, and requirements to implement stricter pollution control measures. This failure can also lead to negative health impacts on residents due to increased levels of pollution in the air. States may be required to develop and implement plans to improve air quality and come into compliance with the standards.

As far as i know Newzealand is the least polluted country in the world, as it has least pollution levels, governments has launched a number of programs to control in the rising of pollution levels previously, therefore it has the best air quality and fresh air.

The Clean Air Act addresses air quality management by regulating emissions of hazardous air pollutants and establishing national air quality standards. It aims to reduce air pollution from various sources, including industrial facilities, vehicles, and power plants. The Act also mandates state implementation plans to achieve and maintain these standards and promotes public health and environmental protection. Additionally, it addresses issues like acid rain, ozone depletion, and greenhouse gas emissions.
