घनत्व में अंतर किसका आधार है
1 परनिस्पंदन
2 आण्विक चलनी
3 गुरूत्वीय पृथक्करण
4 आण्विक आकर्षण
Explanation:
In case of ultrafiltration it is particle size of micron sizes present in liquid or gas are getting filtered. In molecular sieving, permeability of molecular sieve membranes based on the size and shape of the molecules is employed. In gravity separation difference in density of particles is employed In molecular attraction, mainly exchange of cations to anions among given two molecules. In atomic absorption ,elements are identified based on the absorption of optical radiation by free atoms in gaseous state.

निम्न में से कौनसा तत्व यह बताता है कि पृथ्वी पर जीवन है
1 ऑक्सीजन
2 हाइड्रोजन
3 कार्बन
4 आयरन
Explanation:
Life on Earth is based on carbon, likely because each carbon atom can form bonds with up to four other atoms simultaneously. This quality makes carbon wellsuited to form the long chains of molecules that serve as the basis for life as we know it, such as proteins and \(DNA.\)

निम्न में से किसमें केवल एक ही तत्व है
1 संगमरमर
2 हीरा
3 काँच
4 बालूरेत
Explanation:
Diamond is an allotrope of carbon and is therefore, made up of one element, carbon. Glass, on the other hand, is mainly composed of silica and sodium carbonate. Marble is mainly calcium carbonate and sand is composed of silicon dioxide.
