Final answer:
An acetylene cylinder has a pressure of 2175 kPa. The answer is option A.
Step-by-step explanation:
The pressure of an acetylene cylinder is typically measured in kilopascals (kPa). Acetylene is often stored in cylinders at high pressure to keep it in a liquid state. Option A) 2175 kPa represents a pressure value commonly associated with acetylene cylinders.
Kilopascals (kPa) are a unit of pressure in the metric system, and they are commonly used in the context of gas cylinders. In this case, 2175 kPa indicates the pressure of the acetylene gas within the cylinder. It's important to handle and use compressed gases, such as acetylene, with proper safety precautions due to the high pressures involved.
Hence, the answer would be option A.
