The thermodynamic law that explains the movement of heat energy during the refrigeration cycle is the?
Sounds like you are looking for the second law that requires that heat move from warmer source to a cooler sink. This happens when the cold refrigerant absorbs heat and when the compressed refrigerant dumps heat to the cooler surroundings. There will also be some heat dumped to the cooler surroundings by the compressor.
What else can I help you with?
Is the thermodynamic law that explains the movement of heat energy during the refrigeration cycle is the fist law?
No, the thermodynamic law that specifically explains the movement of heat energy during the refrigeration cycle is the second law of thermodynamics. The first law, which is the law of conservation of energy, states that energy cannot be created or destroyed, only transformed. In the refrigeration cycle, the second law governs how heat is transferred from a cooler space to a warmer one using work, which is essential for the refrigeration process to occur.
Which theory explains ATP synthesis chloroplast and mitochondria?
The chemiosmotic theory explains ATP synthesis in both chloroplasts and mitochondria. This theory states that ATP is generated through the movement of protons across a membrane, creating a proton gradient that drives the synthesis of ATP by ATP synthase. In chloroplasts, this process occurs in the thylakoid membrane during photosynthesis, whereas in mitochondria, it occurs in the inner mitochondrial membrane during cellular respiration.
How many revolution the crankshaft make in a four stroke cycle engine to complete on thermodynamic cycle?
The crankshaft makes two complete revolutions to complete one thermodynamic cycle. The crankshaft rotates 180 degrees during each stroke of the engine. Hence a total of two revolutions occur after completion of the four strokes. Chechout "www.howstuffworks.com " to see how crankshaft works.
What causes frictionation to happen in certain blends of refrigerants?
Frictionation in refrigerant blends occurs due to differences in the physical and thermodynamic properties of the individual components, such as boiling points and molecular weights. When a blend is subjected to changes in pressure and temperature during phase transitions, the components may separate, leading to uneven distribution and varying performance. This can result in reduced efficiency and potential system damage if not properly managed in refrigeration systems. Proper blend design and management strategies can help mitigate frictionation effects.
What is approached pressure and temperature increase?
Approached pressure and temperature increase refers to the changes in pressure and temperature in a system as it approaches a specific state or condition, often during processes like compression or heating. In engineering and thermodynamics, this concept is crucial for understanding how substances behave under varying conditions, particularly in systems like engines or refrigeration cycles. The increase in pressure can lead to a corresponding rise in temperature, following the ideal gas law or other relevant thermodynamic principles, influencing efficiency and performance.

She violently suppressed a Sikh independence movement.
What explains the movement of africans to new Spain during the early 1500s?
Deaths among native Americans being used as slaves caused a shortage of workers in the new world.
What is the relationship between isentropic enthalpy and thermodynamic processes?
Isentropic enthalpy is a measure of energy in a system that remains constant during an isentropic process, which is a thermodynamic process where there is no change in entropy. In thermodynamic processes, isentropic enthalpy helps to analyze the energy changes that occur without considering any heat transfer or work done.
What is the net refrigeration effect in the refrigeration cycle?
The net refrigeration effect in a refrigeration cycle is the amount of heat absorbed from the refrigerated space by the refrigerant gas as it evaporates, minus the amount of work done on the refrigerant gas during compression. It represents the actual amount of cooling provided by the refrigeration system.
How can the work done in a thermodynamic process be determined using a PV diagram?
The work done in a thermodynamic process can be determined using a PV diagram by calculating the area under the curve on the graph. The area represents the work done by the system during the process.
What is the relationship between adiabatic expansion and enthalpy change in a thermodynamic system?
During adiabatic expansion in a thermodynamic system, there is no heat exchange with the surroundings. This leads to a change in enthalpy, which is the total heat content of the system. The enthalpy change during adiabatic expansion is related to the work done by the system and can be calculated using the first law of thermodynamics.
How does railway refrigeration works?
Railway refrigeration systems work by using a refrigeration unit installed on the train to cool the air inside the refrigerated cars. The unit typically uses a compressor to generate cold air and a fan to circulate it throughout the car, maintaining a constant temperature to preserve perishable goods during transit. Refrigeration units may be powered by the train's electrical system or by an independent power source.
Is a hot dog refreezable?
Yes it is, as long as it is not expired during it's time of refrigeration prior to freezing.
How does the work from a PV diagram represent the energy transfer in a thermodynamic process?
The work represented on a PV diagram shows the energy transferred during a thermodynamic process. The area under the curve on the diagram represents the work done on or by the system. This helps to understand how energy is transferred and transformed in the process.
How can the pressure volume diagram be used to analyze the thermodynamic processes of a system?
The pressure-volume diagram can be used to analyze the thermodynamic processes of a system by showing how pressure and volume change during different stages of the process. This diagram helps in understanding the work done, heat transfer, and efficiency of the system.
