A given kind of matter has the same chemical makeup and the same chemical properties regardless of its state. Thats because state of matter is a physical property.

Most maps use a grid of lines to help you to find your location. This grid system is called a geographic coordinate system. Using this system you can define your location by two numbers, latitude and longitude. Both numbers are angles between your location, the center of Earth, and a reference line (Figure 2.20).
