Properties of Water Station Lab Station 5. Density. Water is one of the few substances that are less dense as a solid than as a liquid. While most substances contract when they solidify, water expands. This property is due to the hydrogen bonding between water molecules. Part 1. Place the ice cube in the water. Describe what happened below.

If a piece of aluminum with a mass of 3.99 g and a temperature of 100.0 oC is dropped in 10.0 cm3 of water at 21.0 oC, what will be the final temperature of the system? (Hint: Remember the density of water is 1.00 g / mL) A piece of unknown metal with a mass of 5.19 g is heated to 100.00 oC and dropped into 10.0 mL of water at 22.00 oC.

Temperature and salinity (the amount of dissolved salts in the water) affect the density of the water. Ocean salinity differs by small numbers, so oceanographers need to be accurate when measuring salinity. Changes in density caused by wind and currents at the surface affect the deep-ocean currents.
The Temperature of Maximum Density for Water | Actforlibraries.org
This activity explores the impact of temperature and salinity on water density. Cold water is denser than warm water, so it tends to sink. This is because water expands when it warms up – heat energy makes its molecules move around more and take up more space. When water cools, it contracts, becomes denser and sinks. Seawater is denser than ...
