What 3 changes of state absorb thermal energy?
Melting, evaporation, and sublimation are changes of state that absorb thermal energy. During these processes, the particles in a substance gain energy to break intermolecular bonds and overcome attractive forces between them, resulting in an absorption of thermal energy.
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 product absorbs thermal energy?
Materials like water, sand, and concrete can absorb thermal energy due to their high heat capacity. Additionally, phase change materials (PCMs) can absorb and release large amounts of thermal energy during the process of changing phase, such as from solid to liquid.
In a air conditioner is thermal energy absorbed by coolant within pipes?
Yes, in an air conditioner, thermal energy is absorbed by the coolant (usually a refrigerant) within pipes in the evaporator coil. This process helps to cool the air inside the building and transfer the absorbed heat energy outside.
How do you remove thermal energy?
Thermal energy can be removed by transferring it to a cooler object through conduction, convection, or radiation. Common methods to remove thermal energy include using a heat sink, a fan, or a coolant such as water or refrigerants in a cooling system.
Why water is often used as a coolant?
It is often useful as a coolant because it can absorb thermal energy without a large change in temperature.
What is a coolant?
a fluid that is circulated through a machineor other object in order to absorb thermal energy from it and thus control its temperature

Does a refrigerator convert thermal energy to mechanical energy?
Yes coolant is used in a cycle
What energy causes water to evaporate?
For evaporation water absorb thermal energy from the environment.

Will an object will be a net radiator of energy when its thermal energy is less than that of its surroundings?
No, an object will not be a net radiator of energy when its thermal energy is less than that of its surroundings. In this case, the object will instead absorb thermal energy from its surroundings in an attempt to reach thermal equilibrium.
What are gases that absorb thermal energy in the atmosphere called?
Greenhouse gases.
What does a liquid to a solid involve in thermal energy?
To become a solid, a liquid will absorb heat energy.
How the thermal energy of the coolant changes as the coolant flows through the refrigerator?
As the coolant flows through the refrigerator, its thermal energy decreases as it absorbs heat from the interior of the fridge. This heat absorption occurs in the evaporator coil, where the coolant evaporates and transitions from a liquid to a gas. Subsequently, the gaseous coolant flows to the compressor, where it is compressed and its temperature and pressure increase before releasing heat to the surroundings in the condenser coil. Overall, the coolant's thermal energy is transformed as it circulates, facilitating the cooling process inside the refrigerator.

How does thermal energy of solid water change as its melting?
The thermal energy of the water increases as it melts, changing from a solid (ice) to liquid water. For a solid to melt, it is necessary for it to absorb energy from its surroundings.
