1. The problem statement, all variables and given/known data A flat, uniform cylinder of lead floats in mercury at 0 degrees Celsius. Will the lead float higher or lower then the mercury temperature is raised? 2. Relevant equations None. 3. The attempt at a solution Since the mercury is heated, then the density will be lower therefore the lead will float lower? I'm kind of confused because wouldn't it just sink to the bottom? Not remain floating?
