Show answer & explanation
Correct answer: A. (A)-(IV), (B)-(I), (C)-(II), (D)-(III)
Explanation
Mist is an aerosol of liquid droplets formed by condensation of water vapour, so (A)-(IV). Smoke consists of fine solid particles released during incomplete combustion, so (B)-(I). Fume is formed when hot metallic vapours condense, so (C)-(II). Smog of the Los Angeles type is a photochemical product of VOCs and NOx, so (D)-(III). Hence (A)-(IV), (B)-(I), (C)-(II), (D)-(III).कुहासा जलवाष्प के संघनन से बने तरल बिंदुकों का एरोसॉल है, अतः (A)-(IV)। धुआँ अपूर्ण दहन में निकले सूक्ष्म ठोस कणों से बनता है, अतः (B)-(I)। धूम (फ्यूम) धातुओं की गर्म वाष्प के संघनन से बनता है, अतः (C)-(II)। लॉस एंजेलिस प्रकार का स्मॉग VOCs तथा NOx का प्रकाश-रासायनिक उत्पाद है, अतः (D)-(III)। अतः उत्तर (A)-(IV), (B)-(I), (C)-(II), (D)-(III)।More People, Development and Environment questions
