A current of 0.10 A flows through the 25 resistor represented in the diagram to the right. The current through the 80W resistor is:

In the circuit shown in figure, the potentials of B,C and D are :

The energy stored in the capcitor is

The vapour density of a gas is 11.2. The volume occupied by 11.2 g of this gas at N.T.P. is

The r.m.s velocity of hydrogen is  times the r.m.s. velocity of nitrogen. If T is the temperature of the gas,

The difference of  and its reciprocal is

So here the concept of reciprocals and reciprocating the numbers is used. It is basically comparable to flipping the number on its side. Here we were given the numberand the difference between this number and its reciprocal is 105/304.

Which of the following volume (V)- temperature (T) plots represents the behaviour of one mole of an ideal gas at one atmospheric pressure?

The van der Waal’s parameters for gases W, X, Y and Z are

Which one of these gases has the highest critical temperature?

The following graph illustrates

At constant volume and temperature conditions, the rate of diffusion D_A and D_B of gases A and B having densities  and are related by the expression,
