That's kind of a trick question. Specific heat - also known as "heat capacity" is the energy required to change the temperature by a fixed amount. In the case of an isothermal process, the temperature isn't changing.
Since specific heat is defined as (δH/δT), isothermal heat capacity would be (δH/δT)T which means, in English, the change in enthalpy with a change in temperature when the temperature isn't changing... you see the problem. If δT = 0, then δH/δT = ±∞ (positive if heat is added to the system to keep the temperature constant, negative if heat was removed to keep it isothermal)
You could write some equations such that the heat capacity becomes a term in the equation. What you will generally find though is that the heat capacity is multiplying a dT term and when dT is zero, that term drops out and heat capacity is irrelevant for the calculation.
During an isothermal process, the specific heat of a substance remains constant. This is because the temperature of the substance does not change, so the specific heat, which is the amount of heat required to raise the temperature of a substance by one degree Celsius, remains the same.

Why carnot cycle is called a two adiabatic and two isothermal process?
The Carnot cycle consists of two adiabatic processes, where there is no heat transfer, and two isothermal processes, where temperature remains constant. The adiabatic processes involve compression or expansion of the gas without heat exchange, while the isothermal processes occur at constant temperature with heat exchange. This combination allows the Carnot cycle to achieve maximum efficiency in a heat engine.
What is energy is transferred to a gas as heat and work If there is no change in its internal energy the process is known as?
The process is known as an isothermal process. In an isothermal process, the energy transferred to the gas as heat and work results in no change in the gas's internal energy because the temperature remains constant throughout the process.
How does the volume change in an isentropic process?
The entropy of an ideal gas during an isothermal process may change because normally the entropy is a net zero. The change of on isothermal process can produce positive energy.
What is isothermal?
uhnn. cold, hard.and long
Is isothermal expansion reversible under ideal conditions?
Yes, isothermal expansion is considered reversible under ideal conditions because it occurs at a constant temperature, resulting in no change in entropy. This means that the process can be reversed with the same work input, making it reversible.
Which of the following is true of an isothermal process Temperature is constant W equals Q ΔU equals 0 Pressure is constant?
Temperature is constant during an isothermal process. The work done (W) is equal to the heat added (Q). The change in internal energy (ΔU) is zero for an isothermal process. The pressure can vary during an isothermal process, depending on the specific conditions.
What isothermal process?
Isothermal process is a process in which change in pressure and volume takes place at a constant temperature.
What is true about isothermal process?
An isothermal process is one in which the temperature remains constant throughout. This means that the internal energy of the system remains constant as well. In an isothermal process, the heat added to or removed from the system is balanced by the work done by or on the system.

What is different between adiabatic system and isothermal system?
An adiabatic system does not exchange heat with its environment, whereas an isothermal system maintains a constant temperature during a process by exchanging heat with its surroundings. Therefore, in an adiabatic process, the internal energy of the system changes without heat transfer, while in an isothermal process, the temperature remains constant.
What statement best describe the isothermal process?
An isothermal process is one where the temperature remains constant throughout. This means that the internal energy of the system stays the same, as the heat transfer into the system is balanced by the work done by the system. In an ideal gas, this results in no change in the pressure or volume during an isothermal process.
What are examples of isothermal process?
An isothermal process is a change in a system where the temperature stays constant (delta T =0). A practical example of this is some heat engines which work on the basis of the carnot cycle. The carnot cycle works on the basis of isothermal.

Is the work-done in isothermal system is zero why?
In an isothermal process, the temperature of the system remains constant. Since work done is the result of a change in energy, and the temperature does not change, there is no transfer of energy in the form of work during an isothermal process. Thus, the work done in an isothermal system is zero.
What is the difference between isothermal and hyperbolic process?
An isothermal process is one where the temperature remains constant throughout the process, while a hyperbolic process refers to a mathematical curve represented by a hyperbola. In the context of thermodynamics, an isothermal process typically involves heat exchange to maintain constant temperature, while a hyperbolic process is not a specific thermodynamic process but rather a mathematical representation.
