The total pressure of a mixture of two gases is equal to : 

Law of definite proportions when expressed in terms of volumes becomes:

If $$1$$ L of $$O_2$$ at $$15^oC$$ and $$750$$ mm pressure contains $$\text N$$ molecules, the number of molecules in $$2$$ L of $$SO_2$$ under the same conditions of temperature and pressure will be :

The value of molar gas constant is :

The number of molecules in 1 L of oxygen and 1 L of nitrogen at STP will be:

Which of the following is not the unit of the Universal Gas Constant?

At standard temperature and pressure, the volume of 7.1 kg of $$Cl_2$$ will be:

According to the kinetic theory of gases there are:

In a thermally isolated system. Two boxes filled with an ideal gas are connected by a valve. When the valve is in closed position, states of the box 1 and 2, respectively,are (1 atm, $$V_i T$$) and (0.5 atm, 4V, T). When the valve is opened, the final pressure of the system is approximately.

Considering a given mass of a gas by keeping the third variable constant, identify the wrong statements regarding an ideal gas.
(A) With increase in pressure, volume decreases.
(B) With increase in temperature, pressure decreases.
(C) With increase in temperature, volume increases.
