मिथेन (Methane) एक रंगहीन तथा गन्धहीन गैस है जो ईंधन के रूप में उपयोग की जाती है। यह प्राकृतिक गैस का मुख्य घटक है।

मिथेन गैस का रासायनिक सूत्र CH4 है। यह अल्केन श्रेणी का प्रथम सदस्य है और सबसे साधारण हाइड्रोकार्बन है।

जब यह सतह और वातावरण पहुंचता है, यह वायुमंडलीय मीथेन के रूप में जाना जाता है पृथ्वी के वायुमंडल में मीथेन का घनत्व 1750 के बाद से लगभग 150% की वृद्धि हुई है और यह एक ग्रीन हाउस गैस है। मीथेन गैस की खोज सबसे पहले नवंबर 1776 में इटली और स्विट्जरलैंड के वैज्ञानिक एलेसान्द्रो वोल्ता ने की थी। उन्होंने मैगिओर झील के दलदल में इस गैस की पहचान haffman NE kiya की थी ।मेथैन कोयला खानों में इकट्ठा हो जाती है जिससे विस्फोट एवं आग लगने की घटनाएँ हो सकती हैं ।

सोडियम एसोटेट को सोडियम हाइड्रॉकसाइड तथा कैल्सियम ऑक्साइड के साथ गर्म करके मेथैन गैस बनाई जाती है ।

भौतिक गुण (Physical Properties):

यह रंगहीन गैस है । यह जल में अविलेय है । यह वायु से हल्की होती है । यह ग्रीन हाउस प्रभाव पैदा करती है । संपीडित प्राकृतिक गैस (CNG) मुख्यत: मेथैन होती है ।

रासायनिक गुण (Chemical Properties):

(1) मेथैन, वायु में नीले लौ के साथ जलती है और कार्बन डाइऑक्साइड, जल और बड़ी मात्रा में ऊष्मा (55,000 किलो जूल प्रति किलोग्राम) उत्पत्र करती है ।

मेथैन के उपयोग (Uses of Methane):

1. मेथैन का उपयोग घरों एवं उद्योगों दोनों गैसीय ईंधन के रूप में किया जाता है क्योंकि यह जलने पर बडी मात्रा में ऊष्मा उत्पत्र करती है ।

2. आजकल इसका व्यापक रूप में उपयोग स्वचालित वाहनों विशेषकर बसों, कारों एवं आटो रिक्यइओं को चलाने के लिए किया जा रहा है ।

3. यह काजल (कज्जल कार्बन) बनाने के लिए उपयोग में आता है ।

4. मेथैन का उपयोग बहुत बड़ी संख्या में कार्बनिक यौगिकों के निर्माण में किया जाता है, जिनका उपयोग घरेलू एवं उद्योगों में किया जाता है

किसी वस्तु के वेग मे परिवर्तन की दर को त्वरण (ACCELERATION) कहते हैं। इसका मात्रक मीटर प्रति सेकेण्ड2 होता है तथा यह एक सदिश राशि हैं।

उदाहरण: माना समय t=० पर कोई कण १० मीटर/सेकेण्ड के वेग से उत्तर दिशा में गति कर रहा है। १० सेकेण्ड बाद उसका वेग बढ़कर ३० मीटर/सेकेण्ड (उत्तर दिशा में) हो जाता है। यह मानते हुए कि इस समयान्तराल में त्वरण का मान नियत है, त्वरण का मान

उदाहरण: माना समय t=० पर कोई कण १० मीटर/सेकेण्ड के वेग से उत्तर दिशा में गति कर रहा है। १० सेकेण्ड बाद उसका वेग बढ़कर ३० मीटर/सेकेण्ड (उत्तर दिशा में) हो जाता है। यह मानते हुए कि इस समयान्तराल में त्वरण का मान नियत है, त्वरण का मान= (३० m/s - १० m/s) / १० सेकेण्ड = २ मीटर प्रति सेकेण्ड2 होगा।
