Question

Consider a piston-cylinder arrangement containing a gas. This system is heated by placing it on the top of a burner. The system undergoes:

• A. a constant pressure process
• B. a constant volume process
• C. an adiabatic process
• D. an isothermal process

Hint:

In a piston-cylinder arrangement, heating the gas while allowing it to expand typically results in a constant pressure process.

Answer 1

The Correct Option is A

Step 1: Process Identification.
In a piston-cylinder setup, heating the system by placing it on a burner causes the gas volume to increase while maintaining constant pressure. This scenario defines a constant pressure process.

Step 2: Option Analysis.
- (A) A constant pressure process occurs during gas expansion with heating. - (B) A constant volume process prevents gas expansion. - (C) An adiabatic process involves zero heat transfer, which is contrary to this situation. - (D) An isothermal process requires constant temperature, which is not indicated.

Final Answer: \[\boxed{\text{A) a constant pressure process}}\]
