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 a pure substance is heated or cooled but does not change state the energy as heat is the what?
The energy as heat is being used to increase or decrease the temperature of the pure substance. This process involves changing the internal energy of the substance without causing a phase transition.
What is the change in the internal energy of a system that absorbs 2.500J of heat and that does 7.655J of work on the surroundings is?
The change in internal energy is the sum of heat added to the system and work done by the system on the surroundings. So, the change in internal energy is 2.500J (heat absorbed) - 7.655J (work done), resulting in a change of -5.155J.
Is it a chemical or physical change when energy in food molecules is transferred into molecules of ATP?
It is a chemical change. The process involves breaking down the chemical bonds in food molecules to release energy, which is then used to synthesize ATP molecules through chemical reactions within the body.
What is the transferred to an object when work is done?
When work is done on an object, energy is transferred to the object. This can result in a change in the object's motion, position, or internal energy.
Is in the adiabatic process change in internal energy is equal to change in work done?
In an adiabatic process, where there is no heat exchange with the surroundings, the change in internal energy is equal to the negative of the work done. This relationship is a result of the first law of thermodynamics, which states that the change in internal energy of a system is equal to the heat added to the system minus the work done by the system.
If 800 joules of heat are added to a gas in an isochoric process what is the change in its internal energy?
The change would be 100 joules, because an isochoric system can not perform the work.
If 400 J of heat are added to a gas in an isochoric process comma what is the change in its internal energy?
In an isochoric (constant volume) process, there is no change in volume, so the work done is zero. Therefore, all the heat added goes into increasing the internal energy of the system. The change in internal energy of the gas would be equal to the heat added, which in this case is 400 J.
Is heat only transferred if there is no temperature change?
Heat can be transferred even if there is no change in temperature. Heat transfer occurs when energy moves from a warmer object to a cooler object, leading to a change in internal energy without necessarily changing the temperature.
A system gives off 196 kJ of heat to the surroundings and the surroundings do 4.20 x 10 2 kJ of work on the system What is the change in internal energy of the system?
The change in internal energy of the system can be calculated as the sum of heat transferred to the surroundings and work done on the system. In this case, it would be: Change in internal energy = Heat - Work Change in internal energy = 196 kJ - 420 kJ Change in internal energy = -224 kJ (Note the negative sign indicates a decrease in internal energy)
What is transferred when you see a change in the environment?
Energy is being transferred when you see a change in the environment.
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.
What kind of transfer of one unit of energy must occurred?
For a transfer of one unit of energy to occur, energy must be transferred in the form of work or heat between systems. This transfer can involve a change in the internal energy of the systems or a change in the kinetic or potential energy of the systems. The amount of energy transferred would typically be quantified in terms of joules or other appropriate units.
Which type of energry is being transferreed during phase change?
During a phase change, the energy being transferred is primarily in the form of latent heat. This is the energy required to change the state of a substance (such as from solid to liquid or liquid to gas) without changing its temperature.
Is energy lost or gained when it is transferred. explain?
Energy is neither lost nor gained when it is transferred, according to the law of conservation of energy. Energy can change forms or be transferred from one object to another, but the total amount of energy remains constant. Some energy may be dissipated as heat or sound during the transfer process, but the total energy before and after remains the same.
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.
