Answer:
The density of the liquid in beaker B is less than the that of ice.
Explanation:
Ice will float if its mass is less than the mass of the liquid it displaces.
For example, the density of ice is less than that of water.
A 10 cm³ cube of ice has a mass of about 9 g, while the mass of 10 cm³ of water is 10 g. Thus, 9 g of ice displaces 10 g of water.
The denser water displaces the lighter ice and the ice floats to the top.
If the density of the liquid is <em>less than</em> that of water, say, 8 g/cm³, the ice will displace only 8 g of the liquid. The ice will sink.
Answer:
The word gentle traces back to the Latin word gentlis, meaning “of the same clan,” and at first the world was used to describe people belonging to distinguished families, who were seen as courteous and noble. Nowadays you’re more likely to hear the word used to refer to things that are calm, moderate, and without harshness. The word is often applied to people, but it can be used more broadly to describe anything that is mild, such as "a gentle detergent" or "a gentle reminder."

Magma in the Earth's mantle moves in convection currents. The hot core heats the material above it, causing it to rise toward the crust, where it cools. The heat comes from the intense pressure on the rock, combined with the energy released from natural radioactive decay of elements.
