Gravity limits how much the atmosphere can expand so there would be a limit to how much the volume could change.
Nitrous oxide, also known as laughing gas, is a colorless and odorless gas that is commonly used as an anesthetic in medical procedures and as a propellant in whipped cream canisters.
Hydrocarbons, which are compounds made up of hydrogen and carbon atoms, can contribute to greenhouse gas emissions when they are burned or released into the atmosphere. This is because they trap heat from the sun, causing the Earth's temperature to rise.
Greenhouse gases can come from a variety of sources, including natural processes such as volcanic eruptions and decomposition, as well as human activities such as burning fossil fuels and deforestation.
Nitrous oxide is a potent greenhouse gas and contributes to global warming. It also plays a role in the destruction of the ozone layer and can have negative impacts on human health and the environment.
Efforts are being made to reduce greenhouse gas emissions from hydrocarbons through various means such as promoting the use of renewable energy sources, implementing stricter regulations on emissions from industries, and improving energy efficiency in buildings and transportation.
