इंग्रजी मध्ये DEWAR FLASK म्हणजे काय?
व्हॅक्यूम फ्लास्क
व्हॅक्यूम फ्लास्क एक इन्सुलेटिंग स्टोरेज पोत आहे जो फ्लास्कच्या आजूबाजूच्या परिसरात गरम किंवा थंड राहतो. 18 9 2 मध्ये सर जेम्स दिवाटने शोधून काढला, व्हॅक्यूम फ्लास्कमध्ये दोन बोटे बनवल्या गेल्या आहेत. दोन बोटे दरम्यानचा अंतर हवेत अंशतः रिकामा केला जातो, जवळ-व्हॅक्यूम तयार करते ज्यामुळे वाहतूक किंवा संवहन द्वारे उष्णता स्थानांतरणास प्रतिबंध होतो. विस्तारित कालावधीसाठी आणि औद्योगिक क्षेत्रात अनेक उद्दीष्टांसाठी पिण्याचे गरम किंवा थंड ठेवण्यासाठी व्हॅक्यूम फ्लास्कचा वापर केला जातो.
