How are energy heat and work related?

Answer 1

As J.P. Joule initially proposed, there is a close relationship between work and heat.

It is discovered that a system's internal energy increases with work done on it. To put it another way, this means that the system's constituent particles' thermal energy increases and that this increase is always found to be equal to the amount of work done on the system.

Additionally, it was discovered that when the amount of work done on a system remains constant, the rise in internal energy always occurs in the same way and is actually equal to the work done, regardless of the external agents we use.

Answer 2

Energy, heat, and work are related through the principles of thermodynamics. Heat and work are both forms of energy transfer. Heat is the transfer of thermal energy between systems due to a temperature difference, typically occurring through conduction, convection, or radiation. Work, on the other hand, is the transfer of energy that occurs when a force is applied to an object and causes it to move in the direction of the force.

According to the first law of thermodynamics, also known as the law of conservation of energy, the total energy of an isolated system remains constant. This law states that the change in internal energy of a system is equal to the heat added to the system minus the work done by the system. In equation form:

ΔU = Q - W

Where:

  • ΔU is the change in internal energy of the system
  • Q is the heat added to the system
  • W is the work done by the system

This equation illustrates the relationship between heat, work, and the change in internal energy of a system. In various thermodynamic processes, energy can be transferred between systems as heat or work, but the total energy of the system remains constant.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
