If you have 250 g of coffee at 90°C, what will the final temperature be after the ice cube is added? (Hint: the specific heat capacity of coffee is the same as water) a height of 1.65 m before being brought down into a piece of wood (assume the axe simply drops the 1.65m distance). Assuming all energy is conserved (and the wood does not move), how much heat energy is absorbed by the wood when it is struck by the axe?
