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?

(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

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

Prove that Delta H = Delta U + Delta ngRT.

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")

If Z=(A^(4)B^(1/3))/(CD^(3/2)) ,than relative error in Z (Delta Z)/(Z) is equal to (a) ((Delta A)/(A))^(4)+((Delta B)/(B))^(1/3)-((Delta C)/(C))-((Delta D)/(D))^(3/2) (b) 4((Delta A)/(A))+((1)/(3))((Delta B)/(B))+((Delta C)/(C))+((3)/(2))((Delta D)/(D)) (c) 4((Delta A)/(A))+(1)/(3)((Delta B)/(B))-((Delta C)/(C))-((3)/(2))((Delta D)/(D)) (d) ((Delta A)/(A))^(4)+(1)/(3)((Delta B)/(B))+((Delta C)/(C))+(3)/(2)((Delta D)/(D))
