A) Water (2350 g ) is heated until it just begins to boil. If the water absorbs 5.83×10⁵ J of heat in the process, what was the initial temperature of the water?

Express your answer with the appropriate units.

B) If 125 cal of heat is applied to a 60.0-g piece of copper at 22.0 ∘C , what will the final temperature be? The specific heat of copper is 0.0920 cal/(g⋅∘C) .
