Inflation devices are tools used to increase the pressure of gases or liquids in various applications. Common examples include air pumps for inflating tires, balloons, and sports equipment. These devices can be manual, like hand pumps, or powered, such as electric pumps, making them versatile for different needs. In economic terms, inflation refers to the general increase in prices and the decrease in purchasing power over time. While inflation devices in a physical sense help manage pressure, in economics, they represent the mechanisms that can influence the rate of inflation, such as central banks adjusting interest rates to control money supply.
