Q.1. What happens to the ice cube after putting it in the glass of water?
Q.2. How can you describe the movement of the dye in the warm water?
Q.3. Where does the cold dense water go?
Q.4. How does the temperature of the water affects current?

Q1.) the ice will eventually melt and the water in the glass will also eventually overflow
Q2.) the dye will move faster since higher temperature deffuse dye faster
Q3.) Cold dense water will sink to the bottom of the ocean while warm water is less dense and remains on the surface
Q4.) Temperature and salinity both affect the density of water, resulting in water moving up or down through the ocean layers and moving as currents around the ocean.
Water expands when it warms up – heat energy makes its molecules move around more and take up more space. Because the molecules are more spread out, the density goes down. When water cools, it contracts and becomes denser.
