In the simplest of approaches (from a fire investigators approach):
Specific gravity compares the weight of a certain liquid to water with water being given a value of 1. Less than 1 it floats on water, greater than 1 it sinks.
Vapor density compares the weight of a gas/vapor to dry air which is given the value of 1. Less than 1 it rises, greater than 1 it sinks.
