What are the two kinds of combustion engine there is?

• Efficient

• External

• Internal

• Non-Efficient

Is the transfer of thermal energy with no overall transfer of matter. Occurs within a material or with material that are touching.

• Radiation

• Reflection

• Convection

• Conduction

Is a steam engine; an engine that burns fuel outside the engine.

• Internal combustion engine

• External combustion engine

• External cold-fusion engine

• Internal nuclear-cold-fusion enfine

Most cars use this kind combustion of engine which burns fuel inside the engine.

• Internal combustion engine

• External combustion engine

• External cold-nuclear-fusion engine

• Internal cold-nuclear-fusion engine

In which state of matter is conduction slower than other states?

• Plasma

• Liquid

• Gas

• Solid

Is a material that conducts thermal energy very well.

• 5G conductor

• Thermal conductor

• Knee fluid syrange conductor

• Electric conductor

Is the transfer of thermal energy when particles of a fluid move from one place to another.

• Radiation

• Convection

• Conduction

• All of the above

Most heating system use this kind og heat transfer to distribute thermal energy.

• Radiation

• Convection

• Conduction

• Reflection

Is a device that reverses the normal flow of thermal energy. This device to work on a refrigerant

• Heat pencil

• Heat Pump

• Heat flow

• Heat reversed

Convection curves are important in many natural cycles, for example.....

• The water in a pot getting hot

• Ocean Currents

• Movement of hard rock

• Weather systems
