How To Convert Feet to Kilometers - Worked Example Problem

How To Convert Feet to Kilometers Problem This example problem demonstrates how to convert feet to kilometers. Feet To Kilometers Conversion Problem The average commercial jet flies around an altitude of 32,500 feet. How high is this in kilometers? Conversion Solution 1 foot 0.3048 meters1000 m 1 kmSet up the conversion to the desired unit will be canceled out. In this case, we want km to be the remaining unit.distance in km (distance in ft) x (0.3048 m/1 ft) x (1 km/1000 m)distance in km (32500 x 0.3048/1000) kmdistance in km 9.906 km Answer 32,500 feet is equal to 9.906 kilometers.Many conversion factors are difficult to remember. Feet to meters would fall into this category. An alternate method to perform this conversion is to use multiple easily remembered steps.1 foot 12 inches1 inch 2.54 centimeters100 centimeters 1 meterUsing these steps we can express a distance in meters from feet as:distance in m (distance in ft) x (12 in/1 ft) x (2.54 cm/1 in) x (1 m/100 cm)distance in m (distance in ft) x 0.3048 m/ftNote this gives the same conversion factor as above. The only thing to watch out for is for the intermediate units to cancel out.

Phase Definition and Examples

Phase Definition and Examples In chemistry and physics, a phase is  a physically distinctive form of matter, such as a solid, liquid, gas, or plasma. A phase of matter is characterized by having relatively uniform chemical and physical properties. Phases are different from states of matter. The states of matter (e.g., liquid, solid, gas) are phases, but matter can exist in different phases yet remain in the same state of matter. For example, liquid mixtures can exist in multiple phases, such as an oil phase and an aqueous phase. The term phase may also be used to describe equilibrium states on a phase diagram. When phase is used in this context, its typically synonymous with a state of matter because the qualities that describe the phase include the organization of matter as well as variables such as temperature and pressure. Phases of Matter The distinct phases used to describe states of matter include: Solid: Closely packed particles with a fixed volume and shapeLiquid: Fluid particles with a fixed volume but variable shapeGas: Fluid particles with neither a fixed volume nor shapePlasma: Charged particles with no fixed volume or shapeBose-Einstein condensate: A diluted, cold boson gasMesophases: Intermediate phases between solid and liquid There may be multiple phases within a single state of matter. For example, a bar of solid iron may contain multiple phases (e.g., martensite, austenite). An oil and water mixture is a liquid that will separate into two phases. Interface At equilibrium, there is a narrow space between two phases where the matter doesnt exhibit properties of either phase. This region, known as interface, may be very thin, yet can exert significant effects.
