Potassium superoxide (KO2) can simulate a plant-type action by consuming carbon dioxide (CO2) gas and releasing oxygen (O2) gas. The other product is potassium carbonate (K2003). When the equation for this process is balanced, it shows that

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.
