When work is done by a system an no heat added to it the temperature of the system?
When work is done by a system with no heat added, the temperature of the system generally decreases. This is due to the fact that work done by the system often involves the system losing energy in the form of work, causing its internal energy and therefore its temperature to decrease.
What indicates that energy has been added to or removed as heat or work from system?
An increase in temperature indicates that energy has been added as heat to a system, while a decrease in temperature indicates that energy has been removed as heat. Additionally, changes in volume or pressure can indicate that work has been done on or by the system.
What is the relationship between heat added to a system and the internal energy and external work done by the system-?
When heat is added to or is absorbed by a system, its internal energy increases. The amount of external work a system can do essentially refers to the amount of energy it can transfer to something else. So when internal energy increases, so does the external work done by the system.
How are heat work and internal energy related?
Heat, work, and internal energy are all forms of energy transfer. Heat is energy transfer due to a temperature difference, work is energy transfer due to a force acting through a distance, and internal energy is the total energy of a system. The change in internal energy of a system is the sum of the heat added to the system and the work done on the system.
How does an isothermal process work in thermodynamics?
In an isothermal process in thermodynamics, the temperature of the system remains constant throughout the process. This means that the heat added to or removed from the system is balanced by the work done by the system, resulting in no change in temperature. This allows for easier calculations and analysis of the system's behavior.

What three processes occur in every heat engine?
1. a high temperature source is used to remove thermal energy from 2. a low temperature receptacle is where the thermal energy can be received 3. thermal energy is converted to work I'm only a high school Advanced Physics student, but I'm almost certain this is right.
What is the reverse of heat engine operate?
The reverse of a heat engine operating is a refrigeration system operating. In a heat engine, heat is converted into work, while in a refrigeration system, work is used to transfer heat from a lower temperature to a higher temperature.
When does the internal energy increases?
The internal energy of a system increases when energy is added to the system through heat transfer or work done on the system. This can result in an increase in temperature, change in phase, or other forms of internal energy change.
What is the relationship between the change in internal energy (delta U) and the heat and work interactions in a thermodynamic system?
The change in internal energy (delta U) of a thermodynamic system is equal to the heat added to the system minus the work done by the system. This relationship is described by the first law of thermodynamics, which states that the change in internal energy is equal to the heat added to the system minus the work done by the system.
How do you add energy and matter?
Energy can be added to a system by transferring heat, doing work, or through chemical reactions. Matter can be added by physically introducing it into the system through processes like mixing, injection, or diffusion. Both energy and matter can be added in ways that cause changes in the system's properties, such as temperature, pressure, or composition.
A system that does no work but which receives heat from the surroundings has?
A system that does no work but receives heat from the surroundings is referred to as a heat engine. This is because even though the system is not performing any mechanical work, it is still able to convert some of the heat energy it receives into other forms of energy, such as thermal energy.
If 425 joules are absorbed from the higher temperature reservoir and 295 joules of that is passed on to the lower temperature reservoir how much work has been done by the system?
To calculate the work done by the system, we can use the formula for efficiency: Efficiency = Work output / Heat input. First, let's determine how much heat is not passed on to the lower temperature reservoir: 425 - 295 = 130 J. Thus, the work done by the system is the heat that is not passed on, which is 130 joules.
