(d)none of these.(ix) सूर्य में ऊर्जा का स्रोत है(अ) विखण्डन प्रक्रिया(ब) संलयन प्रक्रिया(स) रासायनिक प्रक्रिया |
|
Answer» Answer: (ब) संलयन प्रक्रिया Explanation: जब दो हल्के नाभिक परस्पर संयुक्त होकर एक भारी तत्व के नाभिक की रचना करते हैं तो इस प्रक्रिया को नाभिकीय संलयन कहते हैं। नाभिकीय संलयन के फलस्वरूप जिस नाभिक का निर्माण होता है उसका द्रव्यमान संलयन में भाग लेने वाले दोनों नाभिकों के सम्मिलित द्रव्यमान से कम होता है। द्रव्यमान में यह कमी ऊर्जा में रूपान्तरित हो जाती है। जिसे अल्बर्ट आइंस्टीन के समीकरण E = mc2 से ज्ञात करते हैं। तारों के अन्दर यह क्रिया निरन्तर जारी है। सबसे सरल संयोजन की प्रक्रिया है चार हाइड्रोजन परमाणुओं के संयोजन द्वारा एक हिलियम परमाणु का निर्माण। 41H1 → 2HE4 + 2 पोजिट्रान + ऊर्जा[2] 1H2 + 1H2 → 2He4 + 23.6 MeV 1H3 + 1H2 → 2He4 + 0n1 + 17.6 MeV[3] 1H1 +1H1 +1H1 +1H1 = 2He4 + 21β0 + 2V + 26.7 MeV[4] इसी नाभिकीय संलयन के सिद्धान्त पर हाइड्रोजन बम का निर्माण किया जाता है। नाभिकीय संलयन उच्च ताप (१०७ से १०८० सेंटीग्रेड) एवं उच्च दाब पर सम्पन्न होता है जिसकी प्राप्ति केवल नाभिकीय विखण्डन से ही संभव है। सूर्य से निरन्तर प्राप्त होने वाली ऊर्जा का स्रोत वास्तव में सूर्य के अन्दर हो रही नाभिकीय संलयन प्रक्रिया का ही परिमाण है। सर्वप्रथम मार्क ओलिफेंट निरन्तर परिश्रम करके तारों में होने वाली इस प्रक्रिया को १९३२ में पृथ्वी पर दोहराने में सफल हुए, परन्तु आज तक कोई भी वैज्ञानिक इसको नियंत्रित नहीं कर सका है। इसको यदि नियंत्रित किया जा सके तो यह ऊर्जा प्राप्ति का एक अति महत्त्वपूर्ण तरीका होगा। पूरे विश्व में नाभिकीय संलयन की क्रिया को नियंत्रित रूप से सम्पन्न करने की दिशा में शोध कार्य हो रहा है। |

उत्प्रेरक साम्यावस्था में परिवर्तन नहीं कर सकता है। सत्य /असत्य लिखिए |
|
Answer» जब किसी रासायनिक अभिक्रिया की गति किसी पदार्थ की उपस्थिति मात्र से बढ जाती है तो इसे उत्प्रेरण (CATALYSIS) कहते हैं। जिस पदार्थ की उपस्थिति से अभिक्रिया की गति बढ जाती है उसे उत्प्रेरक (CATALYST) कहते हैं। उत्प्रेरक अभिक्रिया में भाग नहीं लेता, केवल क्रिया की गति को प्रभावित करता है। औद्योगिक रूप से महत्वपूर्ण रसायनों के निर्माण में उत्प्रेरकों की बहुत बड़ी भूमिका है, क्योंकि इनके प्रयोग से अभिक्रिया की गति बढ जाती है जिससे अनेक प्रकार से आर्थिक लाभ होता है और उत्पादन तेज होता है। इसलिये उत्प्रेरण के क्षेत्र में अनुसंधान के लिये बहुत सा धन एवं मानव श्रम लगा हुआ है। |
