" triangle "

If in triangle ABC and triangle PQR for some one-one correspondence if (AB)/(QR)=(BC)/(PR)=(CA)/(PQ) then: a) triangle PQR~triangle ABC b) triangle PQR~triangle CAB c) triangle CBA~triangle PQR d) triangle BCA~triangle PQR

Equilateral triangles I,Ill and IV are such that the altitude of triangle I is the side of triangle II,the altitude of triangle II is the side of triangle and the altitude of the triangle is the side of triangle IV.If the area of triangle I is 2cm^(2), then the area (incm ) of triangle IV is:

In Delta PQR~=Delta EFD, Which side of Delta PQR equals ED? Which angle of Delta PQR equals /_E?

How Delta H, Delta S and Delta G changes during adsorption ?

It is given that Delta ABC~Delta PRQ and (BC)/(QR)=(2)/(3) " then " (ar (Delta PQR))/(ar (Delta ABC))=?

Prove that Delta H = Delta U + Delta ngRT.

(A) The thermodynamical reaction proceeds forward if Delta G is negative in the equation Delta G = Delta H - T Delta S (R) If Delta S and Delta H are positive and with increasing temperature, T Delta S increases

For isothermal expansion of an ideal gas into vacuum, among the following how many are zero, Pext, g, Delta T, Delta U, Delta H, Delta S, Delta G, Delta S_("surr"), Delta S_("total")
