Solution Transportation of gases in humans: Breathing is the process via which air enters the lungs through the nasal cavity. Gases are exchanged at the alveolar surface of the bronchioles. Oxygen enters the blood capillaries surrounding the alveoli and is carried by the RBCs to every tissue of the body.

Complete answer: The liquefaction of atmospheric gases means converting them into the liquid. But the atmospheric gases such as nitrogen, oxygen, etc. exist in liquid form only at significantly low temperature for example at −150∘Cor −200∘C − 150 ∘ C o r − 200 ∘ C .

The model, called the kinetic theory of gases, assumes that the molecules are very small relative to the distance between molecules. The molecules are in constant, random motion and frequently collide with each other and with the walls of any container. The individual molecules possess the standard physical properties of mass, momentum, and energy.

Greenhouse gases are gas molecules that have the property of absorbing infrared radiation (net heat energy) emitted from Earth’s surface and reradiating it back to Earth’s surface, thus contributing to the phenomenon known as the greenhouse effect.

This heat trapping is known as the greenhouse effect. Just as too little greenhouse gas makes Earth too cold, too much greenhouse gas makes Earth too warm. Over the last century, humans have burned coal, oil, and gasoline in our cars, trucks, planes, trains, power plants, and factories. Burning such fossil fuels produces CO 2 as a waste product.

The alveoli provide a surface where the exchange of gases can take place.

Most Upvoted Answer. How are the alveoli designed to maximize the exchange of gases? Alveoli are small pouches or sacs.About 300 million alveoli occur inside each lung. The whole surface of an alveolus functions as respiratory surface. As there are about 300 million alveoli in each lung, a very large of respiratory surface becomes available for.

Greenhouse gases trap heat and make the planet warmer. Human activities are responsible for almost all of the increase in greenhouse gases in the atmosphere over the last 150 years. 1 The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity, heat, and transportation.

A carbon footprint measures the number of greenhouse gases (GHGs) emitted into the atmosphere due to an individual, organization, or activity. GHGs include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), and they contribute to climate change by trapping heat in the atmosphere and increasing global temperatures.

The noble gases (Group 18) are located in the far right of the periodic table and were previously referred to as the "inert gases" due to the fact that their filled valence shells (octets) make them extremely nonreactive. The noble gases were characterized relatively late compared to other element groups. The History

We usually cannot see gases, so we need methods to detect their movements indirectly. The relative rates of diffusion of ammonia to hydrogen chloride can be observed in a simple experiment. Cotton balls are soaked with solutions of ammonia and hydrogen chloride (hydrochloric acid) and attached to two different rubber stoppers.
