<span>The Ring of Fire is a major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur. In a 40,000 km horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and/or plate movements. It has 452 volcanoes. The Ring of Fire is sometimes called the circum-Pacific belt.

<span>Charles's law states that at a constant pressure, the volume of a given amount of gas is directly proportional to its absolute temperature. Charle's law is also derived from the ideal gas law which states that:
PV = nRT
As you can see, V and T are already directly proportional with each other. The only difference with Charles Law is that pressure was held constant, cancelling out the moles and gas constant.</span>
