What is the value of internal energy in a cyclic process in thermodynamics?
Since internal energy is a state function and a cyclic process always returns to the same state (that's how you define a cyclic process), the value of the the internal energy will remain constant. That is not to say that it doesn't change along the cyclic path during the process - just that it always returns to the same value when the cycle is complete.
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.
When earth cools most of the energy transferred from earth's surface to space is transferred by the process?
Radiation
What process is energy transferred when sound waves travel through the air?
Mechanical energy
Does a compressor change kinetic energy into pressure energy?
into internal energy
The first law of thermodynamics states that the change in the internal energy of a system is equal to the difference in energy transferred to or from the systems as work and?
Assuming you are talking about a closed system, it is the difference in energy transferred to or from the system as work and HEAT.

What is transferred when you see a change in the environment?
Energy is being transferred when you see a change in the environment.

When 430 J of work is done on a system it lost 120 J energy as heat Calculate the value of internal energy change for this process?
The first law of thermodynamics requires that energy input must equal energy output plus energy accumulation. In this case that translates to; 430 J = 120 J + (internal energy change) so Internal energy change = 430 J - 120 J = +310 J (the internal energy increased by 310 Joules)
How is thermal energy transferred from the sun?
By the process of Radiation

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.
How is energy transferred when there is a change of state?
heat
Can internal energy be equal to zero?
Yes, if the process is occurring under an isothermal condition where change in T=0
Difference between enthalpy and internal energy?
Short Answer:The difference between heat and internal energy is that heat is technically a process by which energy is transferred between systems and internal energy is actual total energy of a system.Details:The meaning and use of terms related heat, temperature, energy varies depending on whether one is informally describing thermodynamic processes or one is being rigorous according to the definitions of thermodynamiocs. For most communication, even most scientific communication, the informal understandings are adequate.The nuances of the technical terms requires the study of thermodynamics, but will be (too) briefly described below.Temperature is directly proportional to the amount of kinetic energy the individual particles have within a body.Internal energy of a system is the total energy of the system. It is the sum of the potential and kinetic energies in all forms, including chemical bonds, rest mass, magnetic energy and everything else.Heat is thermal energy transferred to body. It is energy transferred through a temperature difference. Cold objects gain heat from warm ones.Thermal energy is energy associated with temperature. Thermal energy is not kinetic energy or heat. It is not a rigorously defined thermodynamic quantity when taken out of context.Work is force times distance, a mechanical process which changes the total energy of a system and does not require heat.See related links.
