The energy that causes a change of state in a system is typically thermal energy. When thermal energy is added or removed from a system, it can cause the particles within the system to gain or lose kinetic energy, leading to a change in the state of matter (such as melting, freezing, boiling, or condensation).

What is the relationship between energy and force in a physical system?
In a physical system, energy and force are related in that force is the mechanism through which energy is transferred or transformed. Force is what causes objects to move or change their state of motion, and this movement or change in motion involves the transfer or transformation of energy. In other words, force is the agent that acts on an object to change its energy state.
What is an energy state function and how does it relate to the overall energy of a system?
An energy state function is a property of a system that depends only on its current state, not on how it got there. It relates to the overall energy of a system by providing a way to quantify and describe the system's energy based on its current conditions, such as temperature, pressure, and composition.
Is more energy enters a system then leaves it just causes a what?
If more energy enters a system than leaves it, it causes an increase in the internal energy of the system. This could lead to an increase in temperature, changes in pressure, or other internal changes depending on the nature of the system.
How might a system seem to lose energy and what are the potential causes for this loss?
A system may appear to lose energy due to factors such as friction, heat transfer, and external forces doing work on the system. These causes can lead to a decrease in the system's overall energy, making it seem like energy is being lost.
How does thermal energy transform into kinetic energy in a system?
When thermal energy is added to a system, it causes the particles within the system to move faster and increase in kinetic energy. This increase in kinetic energy results in the overall movement and motion of the system, transforming thermal energy into kinetic energy.

Why does friction reduce the efficiency of machines?
Friction requires energy to overcome it. This causes loss of energy in the system. Loss of energy in a system, by definition, is a reduction of efficiency.

What causes changes state of water?
Addition or removal of heat energy.
What happens when energy is absorbed by a system?
When energy is absorbed by a system, it is taken in and used to increase the system's internal energy, which can lead to changes in temperature, state, or other properties of the system.
What is the role of electrical energy in determining whether a system's energy is in a state of potential or kinetic?
Electrical energy plays a crucial role in determining whether a system's energy is in a state of potential or kinetic. When electrical energy is stored in a system, it is in a state of potential energy. This stored energy can be converted into kinetic energy when the electrical energy is released and used to power devices or perform work. In this way, electrical energy helps determine the balance between potential and kinetic energy within a system.
When energy is removed what does the decrease in energy causes the particles in that state to do?
When energy is removed, the decrease in energy causes the particles to slow down or cool down. This can lead to a decrease in movement and a potential change in state, such as from gas to liquid or solid.
What happens when an electron moves from a low energy state to a high energy state?
When an electron moves from a low energy state to a high energy state, it absorbs energy. This absorption of energy causes the electron to jump to a higher energy level or orbit further away from the nucleus. The electron is now in an excited state and can later release this energy in the form of light when it returns to a lower energy state.
Steady state flow process?
In a steady state flow process, the rate of mass or energy entering a system is equal to the rate of mass or energy leaving the system. This results in a constant system state over time with no accumulation of mass or energy within the system. The system properties remain uniform throughout the process under steady state conditions.
