Thermodynamics Question - Should be pretty easy

Ti/Tf) = (Pi/Pf)or:Tf = Ti * (Pf/Pi)Therefore:Final Temperature = Initial Temperature * (Final Pressure/Initial Pressure).In summary, the equation for calculating final temperature when pressure is changing but volume is constant is Tf = Ti * (Pf/Pi).

Homework Statement



I'm trying to understand this concept of pressures and volumes changing and how it effects the temperature. Is my understanding correct so far?

If pressure is changing but volume is constant is

Final Temperature = Initial Temperature + (something) ?

If this is right so far, I'm stuck on coming up with the "something" value. If it is wrong, how can I determine this?

Thank you

Homework Equations


PV = NKT
(U2 - U1) = (1/2) * NKfT

Final Temperature = Initial Temperature + (something) ?

If PV=nRT and V is constant then:

P/T = constant

So:

Pf/Tf = Pi/Ti

or:

Tf/Ti = Pf/Pi

FAQ: Thermodynamics Question - Should be pretty easy

What is thermodynamics?

Thermodynamics is the branch of physics that deals with the study of energy and its transformation from one form to another.

What are the laws of thermodynamics?

The laws of thermodynamics are fundamental principles that govern the behavior of energy in a system. They include the law of conservation of energy, the law of increase of entropy, and the law of decrease of entropy.

How does thermodynamics apply to everyday life?

Thermodynamics plays a crucial role in many everyday processes, such as cooking, refrigeration, and energy production. It also helps explain the behavior of gases, liquids, and solids, and forms the basis of many engineering applications.

What is the difference between heat and temperature in thermodynamics?

In thermodynamics, heat refers to the transfer of energy from one object to another due to a temperature difference. Temperature, on the other hand, is a measure of the average kinetic energy of the particles in a substance.

How is thermodynamics related to entropy?

Entropy is a measure of the disorder or randomness in a system. In thermodynamics, the second law states that the total entropy of a closed system will always increase over time, meaning that energy will tend to spread out and become more disordered.
