The vander wall's equation for a gas is (P+a/V^2)(V-b)=RT Determine the dimensions of a and b hence write the si unit of a and b

Posted by Tejash Sharma 5 years, 8 months ago

CBSE > Class 11 > Physics

1 answers

Ayushi Chaurasiya 5 years, 8 months ago

(P + a/V2) (V - b) = RT P is pressure, V is volume and T is temperature. [P] = [F/A] = [MLT −2/L2] = [ML−1T −2] [V] = [L3] We cannot add or subtract quantities of different dimensions. Therefore [P] = [a/V2] ⇒ [a] = [PV2] = [ML−1T −2 L6] = [M L5 T −2] ∴ [a] = [M L5 T −2] Similarly, [b] = [V] = [L3]

THEY ARE THE TINY PART IN WHICH ANYTHING IN EXISTENCE CAN BE BROKEN (EVEN ATOM MEANS INDIVISIBLE) SO A ATOM DOESNT HAVE A SPECIFIC STRUCTURE IT COMPRISES OF WAVE AND MATTER HENCE WE CAN JUST ASSUME THAT THE ATOM HAS A SPHERICAL STRUCTURE OR ELECTRON REVOLVE IN CIRCULAR ORBIT (NO ONE HAS PROVED IT ) (EVEN IF U THINK OF BOHR ,RUTHERFORD OF OTHERS)(WE JUST MADE A PROBABLE DIAG.
