What happens if work is done on the piston of a cylinder, displacing it upwards?
Understand the Problem
The question is asking about the effect of work done on a piston within a cylinder, specifically focusing on how it impacts internal energy and temperature. This involves understanding the relationship between work, internal energy, and heat transfer according to the laws of thermodynamics.
Answer
The volume inside the cylinder decreases, increasing the pressure and potentially the temperature.
If work is done on the piston of a cylinder, displacing it upwards, the volume inside the cylinder decreases (compression). This increases the pressure and potentially the temperature of the gas or substance inside the cylinder.
Answer for screen readers
If work is done on the piston of a cylinder, displacing it upwards, the volume inside the cylinder decreases (compression). This increases the pressure and potentially the temperature of the gas or substance inside the cylinder.
More Information
The change in temperature depends on whether the process is adiabatic (no heat exchange) or isothermal (constant temperature).
Tips
It is important to consider the direction of force and displacement when determining the sign of work. Compressing the piston is considered positive work.
