The diagrams to the right show the distribution and arrangement of gas particles in two different
containers. According to kinetic-molecular theory,
which of the following statements is true? Check
all that apply.
If the temperatures of both containers are
equal, container A has greater pressure than
container B.
If the volume of container A decreased its
pressure would decrease.
If the pressure in both containers is equal.
container A has a lower temperature than
container B.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

i'm wiling to try and you : )

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
