carbon
A chemical element with the symbol C and atomic number 6. It is a nonmetal and the basis of all known life on Earth, as well as of organic chemistry.
Diamanten und Graphit sind reine Erscheinungsformen von Kohlenstoff.
Diamonds and graphite are pure forms of carbon.
The word is made up of 'Kohle' (coal) and 'Stoff' (substance/material). So it literally means 'coal substance', which points to its origin and its properties as a basic element.
Der menschliche Körper besteht zu einem großen Teil aus Kohlenstoff.
The human body consists largely of carbon.
'Kohlenstoff' (carbon) is a technical term from chemistry and biology. In everyday life, people are more likely to talk about products that contain carbon, such as coal or plastic.
Im Chemieunterricht haben wir den Kreislauf des Kohlenstoffs besprochen.
In chemistry class, we discussed the carbon cycle.
'Kohlenstoff' (carbon) is the first part of many important chemical terms. If you know this word, you can understand others more easily, such as 'Kohlenstoffdioxid' (carbon dioxide, CO₂), 'Kohlenwasserstoff' (hydrocarbon), or 'Kohlenhydrat' (carbohydrate).
Zu viele Kohlenhydrate in der Ernährung können ungesund sein.
Too many carbohydrates in the diet can be unhealthy.
coal
'die Kohle' and 'der Kohlenstoff' look similar and are connected in meaning, but they are not the same thing. 'Kohle' is a material or fuel, for example for heating or grilling. 'Kohlenstoff' is a chemical element. Coal contains a lot of carbon, but as an everyday word, 'Kohle' does not simply consist of this concept. Learners may confuse the words because both are connected to the word stem 'Kohl-'. In everyday language, you say 'Kohle' when you mean the fuel; in chemistry or the natural sciences, you say 'Kohlenstoff'.
Kohlenstoff ist ein wichtiges Element in der Chemie.
Carbon is an important element in chemistry.
Sie legt neue Kohle auf den Grill, weil das Feuer schwächer wird.
