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.
Process where entropy remains the same?
A process where entropy remains the same is an isentropic process. In an isentropic process, there is no net change in the entropy of the system. This typically occurs when there is no heat transfer and the system is adiabatic and reversible.
Equation to calculate heat gained or lost by an object?
c = Q / (m(change in temperature)) Where, c = specific heat capacity Q = amount of heat needed m = mass Change in temperature = initial temperature - temperature(after) Take note that this equation cannot be used in calculating the change in state - melting and boiling Because temperature do not change. We therefore use: Q = lv x m Where, lv = latent heat of vapourisation (for boiling/condensation ONLY) m = mass Q = lf x m Where, lf = latent heat of fusion (for melting/freezing ONLY)
Will the momentum of a system change when a net force acts on a system?
Yes, the momentum of a system will change when a net force acts on it. According to Newton's second law of motion, the change in momentum of a system is directly proportional to the net force acting on it.
If work is greater than heat in the figure then what must be true about the couch?
If work is greater than heat in the context of the figure, it suggests that the couch is likely undergoing a process where more energy is being transferred as work than as thermal energy. This could indicate that the couch is being compressed or moved, resulting in mechanical energy input that exceeds any heat loss or gain. Consequently, the couch may be experiencing a net increase in energy, potentially leading to a change in its state or position.

What is a net heat output?
Net heat output refers to the amount of thermal energy produced by a heating system or process after accounting for any energy losses. It is calculated by subtracting the heat losses from the total heat generated. This metric is important for assessing the efficiency and performance of heating systems in various applications, such as power plants or residential heating. Understanding net heat output helps in optimizing energy use and ensuring effective heating solutions.
When is the change in entropy zero?
The change in entropy is zero when a process is reversible, meaning that the system and surroundings return to their original state without any net change in entropy.

When does the change in entropy equal zero?
The change in entropy equals zero when a process is reversible, meaning that the system and surroundings return to their original state without any net change in entropy.
What term is used to describe when heat gain is equal to heat loss?
The term used to describe when heat gain is equal to heat loss is thermal equilibrium. This means that there is no net change in temperature because the heat gained by a system is equal to the heat lost by the system.
What is the direction of heat flux on isothermal surface?
Direction of heat flux on an isothermal surface is always normal to the surface.
What is the Formula for calculating net acceleration?
Net acceleration = (change in velocity) divided by (time for the change)
If object A is placed on top of object B and is the same temperature as object B How will heat flow between object A and object B?
In this case, no heat will flow between the objects. At least, there will be no "net" heat flow. The objects are said to be in thermal equilibrium, so that any heat exchanged by their molecules is balanced and there is no net change in temperature.
What is net refrigeration?
The net refrigeration effect is the amount of heat each pound of refrigerant absorbs from the refrigerated space. This heat produces useful cooling.
