When air is compressed?
- its density decreases
- it solidifies
- its temperature decreases
-
its temperature increases
- its temperature remains unchanged
The correct answer is: D
Explanation
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.
