What transfer thermal energy from inside a room to outside which is similar to a refrigerator?
An air conditioner operates similarly to a refrigerator by transferring thermal energy from inside a room to the outside. This is achieved through the use of a refrigeration cycle that absorbs heat from inside the room and releases it outside, cooling the indoor space in the process.
What energy transformation takes place in a refrigerator?
In a refrigerator, electrical energy is transformed into thermal energy as the refrigerant absorbs heat from inside the fridge and releases it outside, cooling the interior.
Which of the following cools the air in a household refrigerator?
The compressor is the part of a household refrigerator that cools the air. The function is absorption but the compressor creates the absorption.
What is the function of heat exchange pipes in refrigerator?
Heat exchange pipes in a refrigerator are responsible for transferring heat from the inside of the refrigerator to the outside environment, allowing the refrigerator to maintain a cool temperature inside. The pipes contain a refrigerant that absorbs heat as it evaporates inside the refrigerator and releases it as it condenses outside. This process helps in cooling the interior of the refrigerator.
How the thermal energy of the coolant changes as it flows in a refrigerator?
As the coolant flows through the refrigerator, it absorbs thermal energy from the inside compartments, causing it to evaporate and carry the heat away. The coolant then releases this thermal energy outside the refrigerator, where it condenses back into a liquid state. This continuous cycle helps maintain the desired temperature inside the refrigerator.

In a refrigerator, electrical energy is transformed into thermal energy as the refrigerant absorbs heat from inside the fridge and releases it outside, cooling the interior.
Is refrigerator exothermic or endothermic?
A refrigerator is an endothermic system because it absorbs heat from its interior to keep the contents cool. This process involves the refrigeration cycle, where a refrigerant evaporates and absorbs heat from inside the fridge, then releases that heat to the external environment when it condenses. Thus, the refrigerator removes heat from the inside, making it an endothermic process.
Which of the following cools the air in a household refrigerator?
The compressor is the part of a household refrigerator that cools the air. The function is absorption but the compressor creates the absorption.
What are the components of refrigirator?
The main components of a refrigerator are a compressor, condenser coils, evaporator coils, and a refrigerant. The compressor circulates the refrigerant, which absorbs heat from inside the refrigerator and releases it outside through the condenser coils. The evaporator coils then cool the air inside the refrigerator.

The pipes contain a refrigerant that absorbs heat as it evaporates inside the refrigerator and releases it as it condenses outside. This process helps in cooling the interior of the refrigerator.
What is the role of refrigerant in a refrigerator and how does it contribute to the cooling process?
The refrigerant in a refrigerator plays a crucial role in absorbing and releasing heat, which helps to cool the interior of the refrigerator. As the refrigerant evaporates, it absorbs heat from the inside of the refrigerator, making it cold. Then, as the refrigerant condenses, it releases the heat outside the refrigerator, maintaining a cool temperature inside.
How the thermal energy of the coolant changes as it flows in a refrigerator?
As the coolant flows through the refrigerator, it absorbs thermal energy from the inside compartments, causing it to evaporate and carry the heat away. The coolant then releases this thermal energy outside the refrigerator, where it condenses back into a liquid state. This continuous cycle helps maintain the desired temperature inside the refrigerator.
What is the substance that absorbs and releases heat in a cooling system?
The substance that absorbs and releases heat in a cooling system is called the refrigerant. When the refrigerant absorbs heat from the surroundings, it evaporates and carries the heat away. When the refrigerant releases the heat, it condenses back into a liquid state, ready to absorb heat again.
How does a refrigerator keep stuff cool?
A refrigerator uses a refrigeration system to remove heat from the interior, keeping the inside cool. It does this by circulating a refrigerant through a series of coils where it absorbs heat from inside the fridge and releases it outside. The insulation in the walls of the refrigerator helps to maintain the cool temperature by trapping the cold air inside.
What are two changes of state of the refrigerant necessary to operate the refrigerator?
The two changes of state of the refrigerant necessary to operate the refrigerator are vaporization (absorbs heat from the refrigerator to cool it down) and condensation (releases heat to the surrounding environment to maintain cooling). These processes occur in the evaporator and condenser coils within the refrigeration system.
How does an air conditioner work to cool down a room?
An air conditioner cools down a room by taking in warm air, removing the heat from it using a refrigerant, and then blowing out cooler air into the room. The refrigerant absorbs the heat from the air inside the unit, then releases it outside, resulting in a cooler indoor temperature.
