A particular sidechain has a dihedral angle for which the energy is governed by the following equation: a. What is the energy of a sidechain with an angle of 60°? b. With an angle of 90°? c. What is the relative population of sidechains with an angle of 60° versus 90° at 300 K?

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.

Most metamorphosis processes take place
