SUMMARY
When the temperature of mercury is raised, its density decreases, which affects the buoyancy of a flat, uniform cylinder of lead floating in it. As the mercury expands and its density lowers, the lead will float higher in the mercury. This conclusion is based on the principle that the buoyant force acting on the lead is determined by the density of the fluid, which decreases with increasing temperature. Therefore, the lead does not sink but rather rises as the mercury is heated.
