• conduction
• vaporization
• radiation

The diagram to the right shows a solid iron bar that is being heated in a flame. The primary method of heat transfer in the solid iron bar is—

• convection
• conduction
• absorption
• radiation

What is the definition of temperature?

• Is everything that can produce a change in matter.

• Everything conteins a certain amount of thermal energy that we can measure.

• Is the transfer of thermal energy from one type of matter with a higher temperature to another type of matter with a lower temperature.

• Has got kinetic energy. It originates from something vibrating. Is movement.
