In a given species of tobbaco there is 0.1 mg of virus per c.c. The mass of virus is $$4 \times 10^{7}$$ Kg per kilomol. The number of the molecules of virus present in 1 c.c. will be

A vertical cylindrical vessel separated in two parts by a frictionless piston free to move along the length of a vessel. The length of vessel is 90 cm and the piston divides the cylinder in the ratio 2 : 1. Each of the two parts contain 0.1 mole of an ideal gas. The temperature of the gas is $$27^{o}$$C in each part. The mass of the piston is

At what temperature the linear kinetic energy of a gas molecule will be equal to that of an electron accelerated through a potential difference of 10 volt?

One gram mol of helium at 27$$^{0}$$ C is mixed with three gram mols of oxygen at 127$$^{0}$$ C at constant pressure. If there is no exchange of heat with the atmosphere then the final temperature will be

The mean molecular energy of gas at 300 K will be

The degrees of freedom of a diatomic gas at normal temperature is

Equal masses of $$N_{2}$$ and $$O_{2}$$ gases are filled in vessel A and B. The volume of vessel B is double of A. The ratio of pressure in vessel A and B will be

A partially inflated balloon contains 500 m$$^{3}$$ of helium at 27$$^{0}$$ C and 1 atm pressure. The volume of the helium at an altitude of 6000 m, where the pressure is 0.5atm and the temperature is -3$$^{0}$$C is

The temperature of gas is increased from 27$$^{o}$$C to 127$$^{o}$$C. The ratio of its mean kinetic energies will be

Figure shows a cylindrical tube of cross-sectional area A filled with two frictionless pistons. The pistons are connected through wire. The tension in the wire if the temperature rises from T$$_{0}$$ to 2T$$_{0}$$ is (Initial pressure is P$$_{0}$$, atmospheric pressure)
