True. When an electrical current flows through a resistor, such as in a light bulb or a heating element, resistance to the flow of electrons generates heat energy. This process is known as Joule heating.
true
True. Heat transfer is the movement of energy from a warmer object to a cooler object.
True, when a gas changes into a liquid, it releases energy, typically in the form of heat. This process is called condensation.
True. Energy is the capacity to do work or produce heat. It can exist in many forms, such as kinetic, potential, thermal, and chemical energy.
Yes, it's true. When a light bulb is turned on, most of the electrical energy is converted into heat, but some of it is also converted into light energy. This is what allows the light bulb to produce light.

False
true
True
True that electrical devices generate some amount of heat.
False its not possible to convert all heat into work as some of its being used as energy APEX
It is true that when bonds are broken there is chemical reaction. Then heat energy is released.
true, when ice changes to a liquid it asorbs heat energy .
True. Heat transfer is the movement of energy from a warmer object to a cooler object.
True, when a gas changes into a liquid, it releases energy, typically in the form of heat. This process is called condensation.
False. The thermal energy itself is the heat, whether or not it happens to be flowing.Another AnswerFalse. Heat is energy in transit from a body at a higher temperature to a body at a lower temperature.The term, 'thermal energy', is long-obsolete, and doesn't describe 'heat'. It has been replaced by the term 'internal energy' which describes the energy due to the vibration of the molecules/atoms that make up an object.
