A solid block of substance is 74.0 cm x 55.0 cm x 35.0 cm and has a mass of 569 kg. Assuming that it did not chemically react with water or dissolve in it, would it float in the water? Remember to change kg to g. Show your work!

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.
