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.

What is the relationship between the change in entropy at constant volume and the thermodynamic property of a system?
The change in entropy at constant volume is related to the thermodynamic property of a system because entropy is a measure of the disorder or randomness of a system. When there is a change in entropy at constant volume, it indicates a change in the system's internal energy and the distribution of energy within the system. This change in entropy can provide insights into the system's behavior and its thermodynamic properties.
What is the relationship between the internal energy of an ideal gas and its thermodynamic properties?
The internal energy of an ideal gas is directly related to its thermodynamic properties, such as temperature, pressure, and volume. Changes in these properties can affect the internal energy of the gas, and vice versa. The internal energy of an ideal gas is a measure of the total energy stored within the gas due to its molecular motion and interactions.
What is the relationship between work, heat, and the change in internal energy (U) in a thermodynamic system?
In a thermodynamic system, the change in internal energy (U) is equal to the work done on or by the system plus the heat added to or removed from the system. This relationship is described by the first law of thermodynamics, which states that the total energy of a system remains constant.
What is the relationship between the internal energy of a closed system and its thermodynamic properties?
The internal energy of a closed system is a measure of the total energy contained within the system, including the kinetic and potential energies of its particles. This internal energy affects the thermodynamic properties of the system, such as temperature, pressure, and volume. Changes in the internal energy can lead to changes in these properties, as described by the first law of thermodynamics.
When should one choose to use internal energy or enthalpy in a thermodynamic analysis?
One should choose to use internal energy when focusing on the system's energy changes, and enthalpy when considering heat transfer at constant pressure.
What is the impact of a change in entropy at constant volume on a system's thermodynamic properties?
A change in entropy at constant volume affects a system's thermodynamic properties by influencing its internal energy and temperature. When entropy increases, the system becomes more disordered and its internal energy and temperature also increase. Conversely, a decrease in entropy leads to a decrease in internal energy and temperature. Overall, changes in entropy at constant volume play a crucial role in determining the behavior and characteristics of a system in thermodynamics.
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.
When should one use enthalpy instead of internal energy in thermodynamic calculations?
Enthalpy should be used instead of internal energy in thermodynamic calculations when the system involves a constant pressure and the focus is on heat transfer.
When should one choose to utilize internal energy or enthalpy in a thermodynamic analysis?
One should choose to utilize internal energy when focusing on the system's energy changes, and enthalpy when considering heat transfer at constant pressure in a thermodynamic analysis.

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.
