One gram of activated carbon has a surface area of `1000cm^2` considering complete coverage as well as monomolecular adsorption. How much ammonia at latm and 273K would be adsorbed on the surface of 44/7gr. carbon. If radius of a ammonia molecule is `10^(-8)cm` .........
The surface are of activated charcoal is 10^(3)m^(3)g^(-1) .If effective surface area of ammonia molecule is 0.129nm^(2) and complete monolayer coverage is assumed. how much ammonia at STP could be adsorbed on 10g of charcoal?
A hollow cylinder having external radius 8 cm and height 10 cm has a total surface area of 338 pi cm^2 Find the thickness of the hollow metallic cylinder.
A point charge causes an electric flux of -1.0xx10^(3) Nm^(2)//C to pass through a spherical Gaussian surface of 10.0 cm radius centred on the charge. If the radius of the Gaussian surface were doubled, how much flux would pass through the surface?
A slab of stone of area 3600 cm^(2) and thickness 10 cm is exposed on the lower surface to steam at 100^(@)C . A block of ice at 0^(@)C rests on upper surface of the slab. In one hour 4.8 kg of ice is melted. The thermal conductivity of the stone In js^(-1) m^(-1) k^(-1) is (latent heat of ice = 3.36 xx 10^(5) j//kg )
