A(2,1) b(8,1) C(4,3) D(6,6)
let these be 4 points(vertices) of a quadrilateral
so i calculated it out as
2 1
8 1
4 3
6 6
2 1
multiplying diagonal elements
Area = |(2*1-8*1)+(8*3-1*4)+(4*6-3*6)+(6*1-2*6)/2|=7
but the answer is 14 and it gives different answers for...
and in the water thing...when heat is supplied the enthalpy does increase and also the entropy as the KE of the molecules increase?so how does it explain spontaneity?
ok,well i guess "Thermodynamics is a physical science that studies the effects on material bodies, and on radiation in regions of space, of transfer of heat and of work done on or by the bodies or radiation"
The KE of the particles of the system is changing...isnt it,work is done on the baloon...
thanks guys,but i guess a relevant explanation according to balloon thing would be good,it would be good if u can relate theoretically both enthalpy and entropy
A reaction is Spontaneous means what??a reaction is favorable?
let me give an example:-By taking a Balloon and blowing air into it we are imparting Energy to the Balloon as the KE of the air molecules so was this reaction spontaneous? or the reverse is spontaneous i.e leave the balloon and let...
