General knowledge
Science: combustion is a chemical reaction in which a substance burns in oxygen, giving heat and light; the minimum temperature at which a substance catches fire is its ignition temperature; combustible substances burn easily (paper, wood), non-combustible ones do not (stone, glass).
विज्ञान में combustion (दहन) वह रासायनिक अभिक्रिया है जिसमें कोई पदार्थ ऑक्सीजन में जलकर ऊष्मा और प्रकाश देता है; जिस न्यूनतम तापमान पर कोई पदार्थ आग पकड़े वह उसका ignition temperature (ज्वलन ताप) है; combustible पदार्थ आसानी से जलते हैं (कागज़, लकड़ी), non-combustible नहीं (पत्थर, काँच)।
