Question

Define the terms :-
1:- energy.
2:- temperature .
3:- conduction.
4:- convection.
5:- radiation.

​

Answer 1

Answer:

• Energy : Energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms.

• Temperature : Temperature is a physical quantity that expresses hot and cold. It is the manifestation of thermal energy, present in all matter, which is the source of the occurrence of heat, a flow of energy, when a body is in contact with another that is colder or hotter. Temperature is measured with a thermometer.
• Conduction : Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules.
• Convection : Convection is the process of heat transfer by the bulk movement of molecules within fluids such as gases and liquids.
• Radiation : Radiation is energy that comes from a source and travels through space at the speed of light. This energy has an electric field and a magnetic field associated with it, and has wave-like properties. You

Answer 2

energy:-

Energy is defined as the “ability to do work, which is the ability to exert a force causing displacement of an object.”

temperature:-

Temperature is a physical quantity that expresses hot and cold.

conduction:-

the process by which heat or electricity is directly transmitted through the material of a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.

convection:-

A convection current is a process that involves the movement of energy from one place to another. Convection process only happens in the fluids i.e. in liquids and gases. ... This happens due to the reason that molecules within liquids or gases are free to move.

Radiation:-

Radiation can be described as energy or particles from a source that travels through space or other mediums. Light, heat, microwaves and wireless communications are all forms of radiation
