6 Questions
What is the difference between complete combustion and incomplete combustion?
Complete combustion produces carbon dioxide and water, while incomplete combustion produces carbon monoxide and/or carbon (soot).
What is thermal decomposition?
Thermal decomposition is the breakdown of a compound into simpler substances when heated.
How does pressure affect solids?
Increasing pressure on solids can lead to changes in their physical properties, such as density and compressibility.
Explain the difference between complete combustion and incomplete combustion.
Complete combustion produces carbon dioxide and water, while incomplete combustion produces carbon monoxide and/or carbon (soot).
Describe the factors that affect the loudness and amplitude of sound waves.
The loudness of a sound depends on the amplitude of the sound wave, while the amplitude of a sound wave is affected by the energy of the source and the distance from the source.
Explain the concept of thermal decomposition and provide an example of a substance that undergoes thermal decomposition.
Thermal decomposition is the breakdown of a compound into simpler substances when heated. An example is the decomposition of calcium carbonate (limestone) into calcium oxide (quicklime) and carbon dioxide.
