Refrigerator फ्रिज

Refrigerator
 A refrigerator is a common household appliance that consists of a thermally insulated compartment and a heat pump (mechanical, electronic, or chemical) that transfers heat from the inside of the fridge to its external environment so that the inside of the fridge is cooled to a temperature below the ambient temperature of the room. Refrigeration is an essential food storage technique in developed countries. The lower temperature lowers the reproduction rate of bacteria, reducting the rate of biochemical reactions so the refrigerator reduces the rate of spoilage. A refrigerator maintains a temperature a few degrees above the freezing point of water. Optimum temperature range for perishable food storage is 3 to 5 °C (37 to 41 °F).[1] A similar device that maintains a temperature below the freezing point of water is called a freezer.
फ्रिज
 एक फ्रिज एक सामान्य घरेलू उपकरण है जिसमें एक थर्मल इंसुलेटेड कम्पार्टमेंट और एक हीट पंप (मैकेनिकल, इलेक्ट्रॉनिक या केमिकल) होता है जो फ्रिज के अंदर से लेकर उसके बाहरी वातावरण में गर्मी को स्थानांतरित करता है ताकि फ्रिज के अंदर का हिस्सा ठंडा हो जाए  कमरे के परिवेश के तापमान के नीचे तापमान।  विकसित देशों में प्रशीतन एक आवश्यक खाद्य भंडारण तकनीक है।  कम तापमान जीवाणुओं की प्रजनन दर को कम करता है, जैव रासायनिक प्रतिक्रियाओं की दर को कम करता है इसलिए रेफ्रिजरेटर खराब होने की दर को कम करता है।  एक रेफ्रिजरेटर पानी के ठंड बिंदु से कुछ डिग्री अधिक तापमान बनाए रखता है।  नाशपाती खाद्य भंडारण के लिए इष्टतम तापमान सीमा 3 से 5 ° C (37 से 41 ° F) है। [1]  एक समान उपकरण जो पानी के ठंड बिंदु से नीचे एक तापमान बनाए रखता है उसे फ्रीज़र कहा जाता है।

Key Lessons from the Movie- ‘3 Idiots

Key Lesson from 3Idiot Movie  Key Lessons from the Movie- ‘3 Idiots’: Every movie has a meaning, carrying a message. However, it depends upon the viewer to grab the message and apply the same in life. The bollywood blockbuster ‘3 Idiots’ is an inspiring story of three  students Rancho, Farhan Qureshi and Raju Rastogi who have joined the Imperial College of Engineering. In brief, the five key lessons that we can draw from the movie can well be described below.  Chase excellence, instead of success, and success will follow and run after you: Rancho, who is an orphaned boy, had got interest in engineering since his early childhood. He, right from the very beginning till the end, sticks to his conviction that it is not success in life but excellence that must be pursued with passion. His words, ‘make your passion, your profession’ sets the tone around which the plot of the movie is woven. Rancho pursues his goal with passion and hence emerges as the student of the...
