A gas expands from 4.0 L to 4.5 L against a constant external pressure of 1 atm. The work done by the gas is (1 L-atm = 101.3 J)

The volume of 2.89 g of carbon monoxide at 27^(@)C and 0.821 atm pressure is (A) 2.5 L (B) 4 L (C) 3.5 L (D) 3 L

Subtract: 3l\ (l-4m+5n) from 4l(10 n-3m+2l)

An orbital has l=4 , what are the possible values of m_(l) ? Hint : m_(l) = -1,"…...",0"…......," +l

An orbital has l=4 , what are the possible values of m_(l) ? Hint : m_(l) = -1,"…...",0"…......," +l

If m is the A.M. of two distinct real numbers l and n""(""l ,""n"">""1) and G1, G2 and G3 are three geometric means between l and n, then G1 4+2G2 4+G3 4 equals, (1) 4l^2 mn (2) 4l^m^2 mn (3) 4l m n^2 (4) 4l^2m^2n^2

If coefficient of a^2 b^3 c^4 in(a+b+c)^m (where n in N ) is L(L != 0), then in same expansion coefficient of a^4b^4c^1 will be (A) L (B) L/3 (C) (mL)/4 (D) L/2

Two incoherent sources of intensities l and 4l superpose then the resultant intensity is

The energies of three conservative energy levels L_3,L_2 and L_1 of hydrogen atom are E_0 . (4E_0)/9 and E_0/4 respectively. A photon of wavelength lambda is emitted for a transition L_3 to L_1 .What will be the wavelength of emission for transition L_2 to L_1 ?

Consider the lines L_(1) : x/3 +y/4 = 1 , L_(2) : x/4 +y/3 =1, L_(3) : x/3 +y/4 = 2 and L_(4) : x/4 + y/3 = 2 .Find the relation between these lines.
