Question: 1 / 400

What occurs when air is compressed in a closed space?

The temperature decreases and the volume increases.

The volume decreases and the temperature raises.

When air is compressed in a closed space, the volume of the air decreases because the molecules are forced closer together. According to the principles of thermodynamics, particularly the ideal gas law and the behavior of gases under compression, when the volume decreases, the temperature of the gas tends to rise. This phenomenon can be explained by the fact that as the air is compressed, the kinetic energy of the gas molecules increases due to them being pushed into a smaller space, resulting in a higher temperature.

The correct answer reflects this relationship between volume and temperature during the process of compression. Understanding this behavior is crucial in fields like thermodynamics and engineering, where gas laws play a critical role in system design and analysis.
