How does a sample of water at 38 °c compare to a sample of water at 295 k? the water at 38 °c has a lower average kinetic energy than the sample at 295 k. the water at 38 °c has faster-moving molecules than the sample at 295 k. the water at 38 °c has greater nuclear energy than the sample at 295 k. the water at 38 °c has larger molecules than the sample at 295 k.

lol idk man i guess u gotta ask bill nye the science guy

there is none because earth is stationary and flat.

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.
