1. Color changes.
The Statue of Liberty, though known for its green color, was originally covered in a layer of copper. After a redox (reduction-oxidation reaction) the color changed due to a chemical change.
2. Gas Production
3. Light Produced
Light sticks work as the result of a chemical reaction between hydrogen peroxide and phenol oxalate ester.
4. Temperature Changes
5. Volume Change
If an object is not changing its velocity, then the object is not accelerating. (There’s no acceleration)
It is true that methane, which is a greenhouse gas and contributes to global warming.
A greenhouse gas is a gas that absorbs and emits radiant energy within the thermal infrared range.
Global warming is rise in the average temperature of the Earth's climate system.
Most often greenhouse gases are carbon dioxide (CO2) and methane (molecular formula CH4). These gases come from burning multiple substances: coal, petroleum, plastic and natural gas.
Balanced chemical reaction of combustion of methane:
CH₄ + 2O₂ → CO₂ + 2H₂O
Greenhouse gases are so difficult to measure, because carbone dioxide, methane, chlorofluorocarbons comes from multiple sources, some of which are relatively hard to measure.

When atoms are excited they emit light of certain wavelengths which correspond to different colors. Each element produces a unique set of spectral lines. ... Since no two elements emit the same spectral lines, elements can be identified by their line spectrum.
