Definition of carbon market. A market that is created from the trading of carbon emission allowances to encourage or help countries and companies to limit their carbon dioxide (CO2) emissions. This is also known as emissions or carbon trading. Carbon emissions trading is a way of reducing greenhouse gases produced by polluters.
In a convergent nozzle, there is an increase in velocity and a decrease in pressure, but we know that pressure is inversely proportional to area. Then why is this pressure decreased in convergent nozzle, although there is a decrease in area? The pressure drops in a convergent nozzle because of the Bernoulli Principle. A nozzle is a spout on the end of a hose or pipe used to control the movement of a fluid like water or air. A convergent nozzle is a nozzle that starts big and gets smaller-a decrease in cross-sectional area. As a fluid enters the smaller cross-section, it has to speed up due to the conservation of mass.
-Even a small increase of CO2 stimulates the CO2 receptors to cause a powerful stimulus to increase the rate and depth of respiration that overrides voluntary control. -O2 receptors are not as sensitive and require a 50% increase in O2 before causing a powerful increase in the rate and depth of respiration.
