Lab Goals Lab Goals 1. Understand the concepts of density 2. Measure the density of water at room temperature 3. Observe the effects of temperature on density Do not plug immersion heater into the electrical outlet unless the heater coil is immersed in the water . Always unplug the heater from the outlet before removing the coil from the liquid.

What is Density? What is Density? Density = mass/volume SI Units [g/cm 3 ] or [g/mL] mass density (is proportional to) volume density (is inversely related to) α α 1 Side Note: If two liquids are mixed their volumes are usually additive A solid dissolved in a liquid typically does not effect the volume, but the density is greater than the pure liquid

Importance of Density Importance of Density Every substance has a unique density Determines how substances separate Float vs. Sink Important in how solvents separate e.g. less dense oil floats in water Reason helium floats in air (air is composed of mainly nitrogen which has a greater density than helium)
