1. Heat- the transfer of kinetic energy from one medium or object to another, or form an energy source to a medium or object.
2. Temperature- the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.
3. Thermometer- an instrument for measuring and indicating temperature, typically one consisting of a narrow, hermetically.
4. Conductor- substance or material that allows electricity to flow through it.
5. ThermalEnergy- the energy contained within a system that is responsible for its temperature.
6. Insulator- a material that is poor conductor ( as of electricity or heat).
7. Convection- the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
8. Radiation- the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.
9. Conduction- the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
Examples:
Radiation- Radioactivity, Gamma Rays, Alpha Particle, Beta Particle, Light, Visible Spectrum, Radio wave, Microwave oven, neutron radiation, etc.
Convection- hot air rising above a fire, ice melting, sea breeze, land breeze, blood circulation (warm-blooded animals).
Conduction- Ironing of clothes, a heat transferring into metal pot of water, etc.
