What else can I help you with?
Why is a refrigerator called a thermal energy mover On what scientific principles does it work?
It removes thermal energy on what ever you place on the refrigerator. The first principle is transfer of heat, the second is solidification or vapourization.
What is the unit of thermal resistance?
Thermal resistance is the resistance of a substance or material to the conduction of thermal energy, or heat. For stuff at the high end of the scale, that is, for stuff having a whole lot of thermal resistance, we might use the term thermal insulator.
What has more thermal energy one gram of water at 75 degrees or 100 grams of water at 75 degrees?
(75'C)x(1g) < (75'C)x(100g) .'. The second option has more thermal energy.
What equation can be used to show why a microwave has high energy?
Energy of microwaves is related to wavelength (lambda) and the speed of light (C). Energy equals Planck's Constant (6.6x10^34 Joules*second) multiplied by the speed of light (3.0X10^8 meters/second) divided by wavelength.
In which direction does heat transfer?
The direction that heat flows in is From a warmer object to a cooler object.
Is thermal energy transferred from warmer to cooler or cooler to warmer?
Thermal energy is transferred from warmer objects to cooler objects. This is based on the fundamental principle of the second law of thermodynamics, which states that heat naturally flows from higher temperature regions to lower temperature regions.
Why does thermal energy only move from the warmer object to the cooler object?
Thermal energy moves from warmer objects to cooler objects because of the second law of thermodynamics, which states that heat naturally flows from a higher temperature to a lower temperature until thermal equilibrium is reached. This is due to the tendency of molecules to seek a state of equilibrium and distribute their thermal energy evenly.
Flow of thermal energy from warmer to cooler substances?
Thermal energy flows from warmer substances to cooler substances through the process of heat transfer. This transfer occurs until both substances reach thermal equilibrium, where they have the same temperature. This flow of thermal energy follows the second law of thermodynamics, which states that heat always flows from higher temperature regions to lower temperature regions.
What energy is the total energy of all of the particles in an object always flows from warmer matter to cooler matter?
The total energy is thermal energy, which is the sum of the kinetic and potential energies of all particles. This flow of energy from warmer to cooler matter is due to the second law of thermodynamics, which states that heat naturally flows from higher temperature regions to lower temperature regions until thermal equilibrium is reached.
Does heat travel from cooler to warmer matter?
In thermodynamics, heat is defined as the energy in transfer between a system and its surroundings. In practice we consider the flow from the higher energy state to the lower energy state. In the case of thermal energy, from the body with the higher thermal energy (warmer) to the body with the lower thermal energy (cooler). In general, however, you may define the flow in either direction you wish, though if you define it as from cooler to warmer, the magnitude would be negative.
What is the direction thermal energy flows?
it's from hotter one to the cooler one,because when electron of the body from which it is flowing gets energy and gets excited and goes to its extrime position and they gets colides with another atom and transfers some energy to it . and the 2nd atom to the third atom and so on and the energy gets transmited.
Does thermal energy always travel from cooler to warmer objects?
Well the predictable pattern is when the warmer object always flows energy to the cooler until they both are the same temp
Can thermal energy flow from cooler objects to warmer objects?
No, thermal energy typically flows from warmer objects to cooler objects due to the difference in temperature. This is governed by the second law of thermodynamics, which states that heat naturally flows from areas of higher temperature to areas of lower temperature in order to reach thermal equilibrium.
What is the transfer of thermal energy from warmer regions to cooler regions?
The transfer of thermal energy from warmer regions to cooler regions is called heat transfer. This process occurs through conduction, convection, or radiation depending on the medium through which the heat is transferred. Heat always flows from areas of higher temperature to areas of lower temperature until thermal equilibrium is reached.
What causes thermal energy always formed in an energy conversion?
Thermal energy is always produced in energy conversions due to inefficiencies in the conversion process. Some of the original energy is always lost as heat due to friction, resistance, and other factors. This is known as the Second Law of Thermodynamics.
Is energy gained or lost when it converts from kinetic to thermal due to friction?
The total energy of course won't change - you won't "gain" or "lose" energy (First Law of Thermodynamics). However, note that you are basically converting useful energy into unusable energy (Second Law of Thermodynamics).
What is the English measurement of thermal energy?
Traditionally the BTU (British Thermal Unit), but now we usually use kilojoules
