At same temperature and pressure ,the fraction of masses having equal volumes of `O_(2)` and `SO_(3)` gas is
A) 2:1
B) 2:5
C) 1:2
D) 1:1

A cone and a hemisphere have equal bases and equal volumes the ratio of their heights is 1:2 (b) 2:1 (c) 4:1 (d) sqrt(2)\ :\ 1

A right circular cylinder and a right circular cone have the same radius and the same volume. The ratio of the height of the cylinder to that of the cone is (a) 3:5 (b) 2:5 (c) 3:1 (d) 1:3

Two samples A and B of a gas are initially at the same temperature and pressure are compressed from volume V_1 to V/2 (A isothermally and B adiabatically). The final pressure is

Assertion: Under similar conditions of temperature and pressure, O_(2) diffuses 1.4 times faster than SO_(2) . Reason: Density of SO_(2) is 1.4 times greater than that of O_(2) .

At a given temperature, 1 mole O_(2) occupy 20dm^(3) of volume. Thes volume occupied by 1 equivalent of O_(2) is

Two containers are of equal volume.One contains O_(2) while the other has H_(2) Both are kept at same temperature. The ratio of their pressure will be (rms velocity of these gases have ratio as 1:4) for 1 mole of each gas-

Two metallic spheres S_1 and S_2 are made of the same material and have got identical surface finish. The mass of S_1 is thrice that of S_2 . Both the spheres are heated to the same high temperature and placed in the same room having lower temperature but are thermally insulated from each other. the ratio of the initial rate of cooling of S_1 to that of S_2 is (a)1/3 (b)1/(sqrt3) (c) (sqrt3)/1 (d) (1/3)^(1/3)
