Words Starting With "C"
Our pre-recorded sounds are fast, clear, and natural, spoken by native speakers.
Carbonize
To carbonize means to burn, or heat, something, usually at a high temperature, until it turns into a black, charred, or brittle substance. This process can occur naturally, such as when wood burns, or it can be achieved through human intervention, such as when food is cooked or prepared by high-heat cooking methods. In a broader sense, carbonization can also refer to the process of converting organic materials, such as plants or organic waste, into a solid, carbon-rich fuel source.
Carbonizing
The word "carbonizing" means to convert something, typically organic matter, into carbon. It can also refer to the process of creating carbon particles or deposits, often through high-temperature processes such as combustion or pyrolysis.
