Which thermodynamic process takes place at a constant temperature so that the internal energy of a system remains unchanged?

If a thermodynamic process takes place at a constant temperature it is called "isothermal".
A word of caution however: the internal energy of a system may not remain the same in an isothermal process if the composition or phase changes; e.g. melting ice can be an isodthermal process but there is certainly a change in internal energy when it happens.

The internal energy of an ideal gas depends on?
The one and only macroscopic thermodynamic property that the internal energy of an ideal gas depends on is its temperature.
How does temperature affects the body?
For mammals very little, except for the energy expenditure required to maintain a constant internal temperature.
Is the work-done in isothermal system is zero why?
If a reaction is carried out in constant temperature and constant volume no work is done and heat exchanged with surroundings is equal to the internal energy.
What is the total of potential and kinetic energy of an object?
In microscopic particles, it's called internal energy. In macroscopic object it's called thermodynamic energy
What is the difference between isobaric and isochoric process?
An isobaric process is a thermodynamic-processin which the pressure stays constant: Δp = 0 The term derives from the Greek isos, meaning "equal," and barus, "heavy." The heat transferred to the system does work but also changes the internal energy of the system:
What are thermodynamics?
Thermodynamic properties are specific volume, density, pressure, and temperature. Other properties are constant pressure, constant volume specific heats, Gibbs free energy, specific internal energy and enthalpy, and entropy.
Is internal energy a thermodynamic function?
Yes, internal energy is a thermodynamic function or state function,
What is it called when an animal maintains a constant internal temperature even when it is cold outside?
It is called homeostasis (internal environment maintained at a constant level) or thermostasis (internal heat maintained at a constant temperature). The overall name for the processes by which temperature is controlled is thermoregulation.
How do amphibians maintain a constant internal temperature?
homeostasis
Is the heat supplied to a system always equal to the increase in its internal energywhat thermodynamic variable is defined by zeroth law and first law of thermodynamic?
The heat supplied to a system can increase its internal energy if no work is extracted from the system. If any work is done by the system, then the increase in internal energy will be less than the heat supplied to the system. The thermodynamic variable defined by the zeroeth law is Temperature.
The internal energy of an ideal gas depends on?
The one and only macroscopic thermodynamic property that the internal energy of an ideal gas depends on is its temperature.
How does temperature affects the body?
For mammals very little, except for the energy expenditure required to maintain a constant internal temperature.
What is homostasis?
the maintenance of a constant internal environment e.g blood sugar levels or temperature
How is the pressure and absolute temperature of a gas at constant volume related?
It is change in internal energy. If the volume of the system remains unchanged (isochoric process)then the heat given to the system is entirely utilized to increase the internal energy of that system. It is to be noted that no pressure-voulme work is done in such processes.
What is the maintence of homeostasis?
it is the maintenance of the internal environment of the body like keeping the blood glucose level constant or keeping the body temperature constant
In a thermodynamic system if you reduce the model by half what variables would also be reduced by half?
All quantitative variables will be reduced including: Internal energy Enthalpy Gibbs energy Volume Mass Moles All intensive properties will remain unchanged including: Specific internal energy Specific enthalpy Specific Gibbs energy Specific volume (and its reciprocal density) Temperature Pressure Heat capacity Elasticity Conductivity etc.
What is the medical term meaning ability of an organism to maintain a relatively constant internal temperature?
Homeostasis is the term that describes an organism's ability to regulate and maintain a relatively constant internal temperature, regardless of external conditions.
