What is the scientific definition of the freezing point of a solution? ■ The water/isopropyl alcohol mixture does not always freeze at a constant temperature. Explain why this is the case. ■ If the amount of isopropyl alcohol added was double, would the change in freezing point increase or decrease? Explain the reasoning behind your answer.

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.
