In a nature heat only moves from a hotter object to a cooler object How is it possible for a heat pump to remove thermal energy from a cold object and add it to a hotter object?

work is done by the heat pump. Cold Freon goes outside in tubes and 'boils' at a very low temp and absorbs heat from the cold air outside (it is boiling at a temp below freezing point of water). This is thencompressed (work done by the compressor, things don't naturally increase their pressure) (gas laws - increase pressure causestemp increase if volume is constant), this 'hot' Freon is pumped thru tubes with household air flowing outside the tubes to absorb the heat and warm the house. The cold Freon then goes back outside the house to be start the process over again.

Which way does thermal energy travel?
From the hotter to the cooler
How is thermal equilibrium established?
Thermal equilibrium is established by the transfer of heat energy from the hotter object to the cooler object until both objects are at the same temperature.
What is the energy transferred from a hotter object to a cooler one referred to?
Energy in transit from a hotter body to a cooler body is called HEAT.
When does thermal energy increase?
when it gets hotter
What is the energy transferred from a hotter object to a cooler object called?
The energy itself is called "heat" or thermal energy. The process is called heat transfer and for objects in contact, it is "conduction" (as opposed to convection or radiation).
What can Thermal energy do?
Thermal energy (or heat) flows from a hotter body to a cooler one, and not the reverse
Which way does thermal energy travel?
From the hotter to the cooler
Can thermal energy be cool when its hot?
Yes. But a cooler body has less energy than a hotter object
How is thermal equilibrium established?
Thermal equilibrium is established by the transfer of heat energy from the hotter object to the cooler object until both objects are at the same temperature.
The energy transferred from a hotter object to a cooler one?
The law says that energy can neither be created nor be destroyed. It can only be transferred from one form to another.... And energy always from higher potential to lower potential... Since hotter object is at high potential and cooler object at lower potential, the heat energy will flow from hotter to cooler object.
What is the energy transferred from a hotter object to a cooler one is referred to as?
This is the zeroth law of thermodynamics: objects at different temperatures will form a thermal equilibrium. The first law of thermodynamics says that energy can not be created or destroyed but can only change form. So the cooler object has to get hotter not the other way around.

Energy in transit from a hotter body to a cooler body is called HEAT.

When objects get hotter what kind of energy do they have?
Thermal
