What can remove thermal energy from a colder object and add it to a warmer object?
A device that can remove thermal energy from a colder object and transfer it to a warmer object is called a heat pump. Heat pumps work by extracting heat from a lower temperature source, such as the air or ground, and transferring it to a higher temperature space, like a building. This process is facilitated by using a refrigerant fluid and a compressor.

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.
Explain why this statement is true. It is only possible to make something cold by taking away its thermal energy?
When you remove thermal energy from an object, its particles slow down and the temperature decreases, making the object cold. If you add thermal energy, the particles speed up and the temperature increases, making the object hot. Cold is the absence or lower level of thermal energy, so taking away thermal energy is the only way to make something cold.
What happens if we remove thermal energy to a liquid.?
If thermal energy is removed from a liquid, its temperature will decrease, causing it to cool down. Eventually, if enough energy is removed, the liquid can reach its freezing point and turn into a solid. The process of removing thermal energy from a liquid is known as cooling or chilling.
Does condensation add or remove thermal energy?
Condensation releases thermal energy. As vapor cools and condenses into liquid form, it releases heat energy into its surroundings.
What happens if you remove thermal energy from a liquid?
If thermal energy is removed from a liquid, its temperature will decrease, causing it to eventually solidify if enough thermal energy is removed. The speed at which this occurs depends on the specific properties of the liquid.
Is it possible to use colder things rather than hot things for thermal energy?
Yes. Heat sinks around computer processors are colder than the processors: they "remove" thermal energy from the processors and so stop them from overheating.

How is it possible for a heat pump to remove thermal energy from cold objects and add it to a hotter object?
Basic trick is to make a transfer fluid that is (much) hotter than the "hotter object" at one point in the cycle. Heat still flows from hot to cold ... but note that the system is not overly efficient.
What happens to states of matter when you remove thermal energy?
When thermal energy is added the matter goes slower
What happens when you remove thermal energy from a gas?
When thermal energy is removed from a gas, its temperature decreases and the gas molecules slow down, leading to a decrease in pressure. If enough thermal energy is removed, the gas can undergo a phase change to liquid or solid form, depending on the initial conditions and the gas properties.
Why do some objects feel colder than other objects of the same temperature?
Objects feel colder or warmer depending on their thermal conductivity, which is the ability to transfer heat. Materials like metal or stone have higher thermal conductivity, so they can quickly remove heat from your skin, making them feel colder. Other materials like wood or insulation have lower thermal conductivity and do not draw heat away as quickly, so they feel warmer to the touch.
Is it possible to add or remove energy?
Energy cannot be created or destroyed, but it can be transferred from one form to another. So, it is possible to add or remove energy by converting it between different types, such as kinetic, potential, or thermal energy.
What is the energy conversion in an iron?
When an iron is plugged in, electrical energy is converted into thermal energy through the Joule heating effect. This thermal energy heats up the iron's soleplate, allowing it to transfer heat to clothes and remove wrinkles during ironing.
