Calculating Work Done in a Closed Piston Cylinder Device with V^1.2 = Constant

In summary, thermodynamics is the branch of science that studies the relationships between heat, energy, and work. The laws of thermodynamics are fundamental principles that govern the behavior of energy in a system. Heat is a form of energy that is transferred due to a difference in temperature, while temperature is a measure of the average kinetic energy of particles in a substance. An open system can exchange both matter and energy with its surroundings, while a closed system can only exchange energy. Examples of thermodynamic processes include the expansion of a gas in a cylinder and the heating of water on a stove.

hey guys got this question that i have been stuck on for a while.

air is expanded from 1M Pa at 327 degrees celcius to 200kPa in a closed piston cylinder device. for the process PV^1.2 = constant. calculate the work done during this process

any help will be welcomed

cheers

temperature constant? work done= -pV ?
 
  • #3
if [P(V^1.2) = constant] this is an adibatic process which means that there is no heat added or taken away.
 
  • #4
I have not encountered something like V^1.2 before. Is that right? If so can someone enlighten me about it?
 

FAQ: Calculating Work Done in a Closed Piston Cylinder Device with V^1.2 = Constant

What is thermodynamics?

Thermodynamics is the branch of science that deals with the relationships between heat, energy, and work.

What are the laws of thermodynamics?

The laws of thermodynamics are fundamental principles that govern the behavior of energy in a system. The first law states that energy cannot be created or destroyed, only transferred or converted. The second law states that the total entropy (measure of disorder) in a closed system will never decrease over time. The third law states that the entropy of a pure crystal at absolute zero temperature is zero.

What is the difference between heat and temperature?

Heat is a form of energy that is transferred from one object to another due to a difference in temperature. Temperature, on the other hand, is a measure of the average kinetic energy of particles in a substance.

What is the difference between an open and a closed system in thermodynamics?

An open system is one that can exchange both matter and energy with its surroundings. A closed system, on the other hand, can only exchange energy with its surroundings, not matter.

What is an example of a thermodynamic process?

One example of a thermodynamic process is the expansion of a gas in a cylinder, which involves a change in volume, pressure, and temperature. Another example is the heating of water on a stove, where heat is transferred to the water causing an increase in temperature and a change in the internal energy of the system.
