Methane
Methane is a chemical compound with the chemical formula CH4. It is a colorless, odorless gas and is the simplest hydrocarbon, consisting of one carbon atom and four hydrogen atoms. Methane is a significant component of natural gas and is also produced during the decay of organic matter in the absence of oxygen.
Properties of Methane:
- Formula: CH4
- State: Gas at room temperature and pressure
- Odor: Odorless
- Flammability: Highly flammable
- Solubility: Low solubility in water
Uses of Methane:
Methane has various uses, including:
- As a fuel for heating and cooking
- As a feedstock for the production of chemicals such as ammonia and methanol
- As a source of energy in power generation
- As a fuel for vehicles, particularly in the form of compressed natural gas (CNG)
Environmental Impact:
While methane is a potent greenhouse gas, it also plays a role in the carbon cycle. Methane emissions contribute to climate change and global warming, and efforts are being made to reduce methane emissions through improved waste management, agricultural practices, and the capturing and use of methane as a fuel.
Study Guide:
To study methane, consider the following key points:
- Understand the chemical formula of methane and its basic structure.
- Learn about the sources of methane, including natural gas, anaerobic decay, and human activities.
- Explore the various uses of methane in industry, transportation, and energy production.
- Examine the environmental impact of methane and the efforts to mitigate its contribution to climate change.

LIFE SCIENCE
From Molecules to Organisms: Structures and Processes
Create representations to explain the unique and diverse life cycles of organisms other than humans (e.g., flowering plants, frogs, butterflies), including commonalities such as birth, growth, reproduction, and death.
Unity and Diversity
Construct an argument from evidence to explain the likelihood of an organism’s ability to survive when compared to the resources in a certain habitat (e.g., freshwater organisms survive well, less well, or not at all in saltwater; desert organisms survive well, less well, or not at all in woodlands).
Create models that illustrate how organisms and their habitats make up a system in which the parts depend on each other.
