Before the collision what is the complete Eigen-function of the molecule? assuming the surface is located at x=0, and V (x =0)=0 and tha tthe molecule is located at a position X>>0. which means the molecule can be treated as a free mass in the re..
Kinetic Molecular Theory states that particle collisions are elastic,but energy and collisions of the particles are proportional to the absolute temperature, but the more collisions according to Henry's law, the more gas dissolves.
How much heat (in kJ) is required to warm 16.0g of ice, initially at -11.0 C, to steam at 112.0 C? The heat capacity of ice is 2.09 J/g*C and that of steam is 2.01 J/g*C.
