On average, each person in the industrialized world is responsible for the emission of 10,000 kg of carbon dioxide (CO2) every year. This includes the CO2 that you generate directly, by burning fossil fuels to operate your car or your furnace, as well as the CO2 generated on your behalf by electric generating stations and manufacturing plants. CO2 is a greenhouse gas that contributes to climate change. What is the volume, in m3, of 10,000 kg of CO2 at 20°C and 1.0 atm pressure? To put this in perspective, the volume of a typical hot-air balloon is 3000 m3.
