a loud and romans is orginal sue. what is the best conclusion that can be drawn from this observation?
the concerto d i tgher in the cell than in the liquid, so water is leaving the cel
the concer n of water is higher in the cell than in the liquid, so water is moving in and out of the cell at the same rate
the concerto
the cells the same as in the liquid, so water is moving in and out of the cell at the same rate.
the conc tion of water the cells the same as in the ligud, so water is leaving the cell.

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)

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.
