What is a common application of pneumatic power?

Pneumatic power refers to the use of compressed air to perform work, making it an essential source of energy in various tools and machinery, particularly in construction and manufacturing settings. A common application of pneumatic power is indeed in tools like air hammers and drills, which utilize compressed air to create motion and deliver high levels of force effectively and efficiently. These tools are known for their lightweight nature and high power-to-weight ratio, allowing users to complete tasks such as breaking concrete or drilling holes much more easily than with manual or electric tools.

In contrast, the other options involve different power sources. Powering electric motors relies on electricity, hydraulic lifts utilize hydraulic fluid and pressure rather than air, and refrigeration systems typically function on refrigerant cycles rather than being directly powered by pneumatic systems. This distinction in the source of power helps to highlight why pneumatic power is specifically applicable to tools that rely on compressed air for operation.
