Question

For many purposes we can treat ammonia NH3 as an ideal gas at temperatures above its boiling point of −33.°C. Suppose the temperature of a sample of ammonia gas is lowered from 17.0°C⁢ to −21.0°C, and at the same time the pressure is changed. If the initial pressure was 0.17kPa and the volume increased by 60.0%, what is the final pressure? Round your answer to the correct number of significant digits.

Answer 1

The atmosphere of Earth is composed of nitrogen (about 78%), oxygen (about 21%), argon (about 0.9%) , carbon dioxide (0.03%) and other gases in trace amounts. ... The atmosphere helps to protect living organisms from genetic damage by solar ultravioletradiation, solar wind and cosmic rays.
