HW2. Hi please help with each question in photo. Will give thumbs up!

What mass of water at 26.0 C must be allowed to come to thermal equilibrium with a 2.00-kg cube of aluminum initially at 150C to lower the temperature of the aluminum to 70.0C? Assume any water turned to steam subsequently recondenses. kg Need Help? Read It A student drops two metallic objects into a 120-g steel container holding 150 g of water at 25.C. One object is a 172-g cube of copper that is initially at 77C, and the other is a chunk of aluminum that is initially at 5.0C. To the surprise of the student, the water reaches a final temperature of 25.C, precisely where it started. What is the mass of the aluminum chunk? kg Need Help? Read It
