Gobar gas is a renewable source of energy produced from organic waste such as cow dung. It is also known as biogas. The chief constituent of gobar gas is methane.

Explanation:

Methane is a colorless and odorless gas that is produced through the process of anaerobic digestion. When organic waste such as cow dung is decomposed in the absence of oxygen, it produces methane gas along with other gases such as carbon dioxide and hydrogen.

The composition of gobar gas can vary depending on the type of organic waste used, the temperature and pH of the digestion process, and other factors. However, methane is the primary constituent of gobar gas and typically makes up around 50-70% of the gas produced.

Methane is a potent greenhouse gas and is a major contributor to global warming. However, when produced from organic waste through anaerobic digestion, it can be a sustainable and renewable source of energy. Gobar gas can be used for cooking, heating, and generating electricity, and can help to reduce reliance on fossil fuels.

Overall, gobar gas is an environmentally friendly and sustainable source of energy, and its chief constituent, methane, plays a crucial role in its production.

Gobar gas is a form of biogas produced by the breakdown of organic matter such as animal dung,wastes,manure ,etc by certain bacteria under anaerobic conditions.Methane is the main gas responsible for it which is produced by animal dung containing methanogen.
