3 ημέρες πριν · Methane is a hydrocarbon that is a gas at room temperature (20°C). Its molecular formula is CH 4, so it has one carbon atom and four hydrogen atoms per molecule. It is often found as the main part of natural gas. Methane is a greenhouse gas 22 times more effective than carbon dioxide.
Methane is a chemical compound with the molecular formula CH4. It is the main component in natural gas. Methane is considered the simplest of alkanes, compounds that consist only of hydrogen (H) and carbon (C) elements. Methane is an odorless, colorless, tasteless gas that is lighter than air. When methane burns in the air it has a blue flame.

OVERVIEW. Although there are natural sources of methane, most of the methane that is contributing to global warming is produced through human activities, such as landfill use and raising cattle. In this lesson, students will learn about sources of methane and how methane affects climate.
Methane. Methane is a natural gas emitted by animals (including humans), wetlands, and volcanoes. Excessive amounts are released by intensive cattle farming, landfill waste, and mining coal — a fossil fuel. Together with CO 2, it's one of the leading contributors to global warming. Water Vapor. This is water in its gas form.
Learn about the sources and uses of the greenhouse gas methane with this guide for KS3 chemistry students aged 11-14 from BBC Bitesize.
