Show with a neat sketch a close packed plane and three close packed directions in an fcc unit cell. b) give the relevant miller indices of those plane and directions by choosing suitable x‐y‐z coordinate axes and origin. show the steps involved clearly.

Two metal blocks that have slightly different temperatures are placed next to one another. after five minutes, they both have lower but equal temperatures. according to the law of conservation of energy, what  most likelyhappened? energy was created inside the blocks.energy was destroyed inside the blocks.energy was absorbed into the blocks from outside the system.energy was transferred from the warmer block to the cooler block.
