When air is compressed?
...When air is compressed?
its density decreases
it solidifies
its temperature decreases
its temperature increases
its temperature remains unchanged
Correct answer is D
Compressed air is a gas, or a combination of gases, that has been put under greater pressure than the air in the general environment.
When you pressurize a gas by compressing it into a container, you're putting all those molecules into a smaller volume of space and you're adding potential energy by the compression.
Gay Lussac's Law - states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature.
