In the hot (yellow) water, the water molecules are slightly further apart than in the cold (blue) water. The hot water is less dense and floats on the cold water. When the cold water is placed on top, ...

This week’s experiment looks into how temperature affects water density. For this experiment, you will need a pan, cold and hot water, food coloring and two glasses. Watch the video in the ...

the variation in space and time of temperature and salinity are also important water mass tracers that can be used to map the ocean circulation. Density is usually calculated using a mathematical ...

This experiment demonstrates how water at different temperatures has different densities, creating beautiful layering effects. You'll see how warm and cold water interact and learn about density ...

When room-temperature washers are placed in hot water, the temperature of the washers increases and the temperature of the water decreases. Energy from the water is transferred to the washers. When ...
