Plants make food in their leaves. The leaves contain a pigment called chlorophyll, which colors the leaves green. Chlorophyll can make food the plant can use from carbon dioxide, water, nutrients, and energy from sunlight. This process is called photosynthesis.

कोयला, जिसे आप खरीदते हो तो रंग काला, उपयोग करते हो तो लाल और फेंकते हो तो सफेद होता है |
Explanation:
जब हम किसी लकड़ी को जलाते हैं और जब लकड़ी पूरी तरह से जल चुकी होती है तब हमें कोयला उत्पाद के रूप में प्राप्त होता है |
कोयला पुनः आग जलाने में काम आता है | आपने देखा होगा गांवों में लोग सिगड़ी जलाकर आंच सेकते हैं या आपने सुना होगा की कोयले ईंधन से कुछ समय पूर्व रैलगाड़ी चलती थी | कोयला जब जलता है तब उसका रंग लाल होता है |
कोयला की गुणवत्ता उसमे उपस्थित कार्बन की मात्रा से तय की जाती है |
- एन्थ्रेसाइट (कार्बन की मात्रा 94-98%)
- बिटूमिनस (कार्बन की मात्रा 78-86%)
- लिग्नाइट (कार्बन की मात्रा 28-30%)
- पीट (कार्बन की मात्रा 27%)
जब कोयला जल चुका होता है तो अंत में हमें राख प्राप्त होती है जो की सफेद रंग की होती है |

Fractions represent equal parts of a whole or a collection.
Fraction of a whole: When we divide a whole into equal parts, each part is a fraction of the whole.
Fraction of a collection: Fractions also represent parts of a set or collection.
For example,
There are total of 5 children.
3 out of 5 are girls. So, the fraction of girls is three-fifths ( 3⁄5 ).
2 out of 5 are boys. So, the fraction of boys is two-fifths ( 2⁄5 ).
