Final answer:
It is true that an appliance with a gas hose can be connected to building piping using a quick-disconnect device, which allows for easy maintenance. However, the statement about high-voltage wires being insulated by wrapping the wires is false; they are held aloft by insulating connectors instead. Gas moves from an area of high pressure to an area of low pressure.
Step-by-step explanation:
The statement that an appliance with a gas hose may be connected to building piping by means of a quick-disconnect device is true. Quick-disconnect devices are designed for secure yet easily removable connections, facilitating maintenance or changes in the appliance setup. Devices such as Bunsen burners already use similar principles for entraining air for proper combustion, illustrating the compatibility between gas delivery and quick-disconnect mechanisms.
High-voltage wires, in contrast, are not insulated by wrapping the wires themselves in insulating material. Instead, they are held aloft by insulating connectors meant to prevent conduction of electricity from the wire to the tower. Therefore, the claim that they are wrapped in an insulating material is false. The principle governing the movement of gas, as it moves from an area of high pressure to an area of low pressure, shows the foundation for how these gases are delivered and regulated in appliances and systems.
