An object loses heat because all warmth flows into colder objects. For example, if you are holding a cup of hot cocoa on a cold winter day the heat of the cocoa will go into your cold hands. This is an example of thermal energy.

What generates heat when the motor is running?
The frictional losses and the resistive losses generate heat in a motor
Does heat travel from a hot object or cold object?
heat travel from a hot object first then to cold object!
Heat is transferred from an object that has a thermal conductivity temperature to an object that has a?
Heat is transferred from an object that has a thermal conductivity temperature to another object through heat conduction.
What direction of heat flow when a warm object and a cool object touch?
The heat will transfer to the cooler object.
Is hysteresis loss considered heat loss?
In general even though energy is lost during hysteresis it is not called as heat losses . Generally I2R losses are called as heat losses because in these tye of only in these energy is lost in the form of real heat
How can heat affect the state of an object?
Heat can affect the molecular composition of an object.
What happens to an object's temperature when you heat?
The temperature of the object will rise because of the heat.
The difference of the heat from temperature?
Temperatue- It is the degree of hotness or coldness of an object. Heat - Heat is a form of energy that can be transferred from one object to another object.
What called when transfer of thermal energy from a warmer object to a cooler object?
Heat energy!Heat is the transfer of energy from a warmer object to a cooler object.
Heat always moves from an object of?
Classically speaking, heat always moves from a hot object to a colder object.
Is no heat loss and no core loss the same thing?
No. Core losses would be hysterisis loss and eddy current losses. Heat losses most likely is referring to I2R (I squared R) losses, which is losses due to the resistance of windings, and is dependent upon loading. There are other losses that are not heat related and core related - such as losses due to vibrations (the core is a major player here, but part of the noise is from windings and cooling systems). I've never heard someone refer to losses as "no heat" or "no core". These are fundamentally impossible - there WILL be core losses, and there WILL be I2R losses if you have a transformer and it is loaded.
What is the movement of energy from warmer object to a cooler object?
the movement of energy from a warmer object to a cooler object is called heat transfer
