The density of a gas filled in electric lamp is `0.75kg//m^(3)` . After the lamp has been switched on, the pressure in it increases from `4xx10^(4)` Pa to `9xx10^(4)` Pa. What is increases in `u_("rms")` ?A. 100B. 200C. 300D. None of these
In a glass tube columns of water and mercury appear as shown. This is best attributed to the differences in their:A. densitiesB. molar massesC. surface tensionsD. viscosities
The volume of real gases often exceed those calculated by the ideal gas equation. These deviations are best attributed to the:A. attractive forces between the molecuels in real gases.B. dissociation of the molecuels in real gases.C. kinatic energy of the molecules in real gases.D. volumes of the molecules in rel gases.
A container holds 3 liter of `N_(2(g))` and `H_(2)O_((l))` at `29^(@)C` The prssure is found to be 1 atm The water in container is instantaneously electrolysed to give `H_(2)` and `O_(2)` following the reaction `H_(2)O_(l) rarrH_(2(g)) +(1)/(2)O_(2_(g))` At the end of electrolysis the pressure was found to be `1.86atm` calculate the amount of water present in the container If the aqueous tension of water at `29^(@)C` is `0.04 atm ` .
