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.
The frictional losses and the resistive losses generate heat in a motor
A heat sink is an object that absorbs heat and distributes it evenly throughout an object, typically used in electronic devices to dissipate heat. Heat sinks are designed to efficiently transfer heat away from a hotter object to a cooler surrounding environment.
When radiated heat reaches an object, it can be absorbed, reflected, or transmitted through the object. Absorption occurs when the object takes in the heat energy, reflection happens when the heat is bounced off the object's surface, and transmission occurs when the heat passes through the object.
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
The temperature of the object will rise because of the heat.
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.
Heat energy!Heat is the transfer of energy from a warmer object to a cooler object.
Heat is transferred from an object that has a thermal conductivity temperature to another object through heat conduction.
No, the amount of heat an object has is determined by its temperature and its mass. A hotter object can have more thermal energy (heat) than a cooler object if it has a higher temperature and/or larger mass, but it is not an absolute rule that a hotter object always has more heat.
Heat moves from the warmer object to the cooler object through a process called conduction. The vibration of particles in the warmer object transfers energy to the particles in the cooler object, causing them to heat up.
Heat Absorption As heat energy reaches an object, it can be absorbed, in a similar manner to the way sponges absorb water. Heat enters an object, warming it. The longer the object is exposed to the heat source, the more heat that it absorbs.
Heat has the natural tendency to flow from a warmer to a colder object. If your hand is warmer than the "cold object", then heat will flow from your hand to that object.
