Question

What is the description of a frictionless piston cylinder drvide?

1) A device used to measure the pressure of a gas
2) A device used to convert heat energy into mechanical work
3) A device used to store and release energy
4) A device used to control the flow of fluids

Answer 1

A frictionless piston-cylinder device is used to convert heat energy into mechanical work.

Step-by-step explanation:

A frictionless piston-cylinder device is a device that is used to convert heat energy into mechanical work. This device consists of a piston attached to a cylinder, where a gas is heated and expands, pushing the piston and performing work. The absence of friction in this device allows for efficient conversion of heat energy into mechanical work.
